Further, the driving device 1 has a latch mechanism 20 that is a mechanism for maintaining the second state of the clutch mechanism 10 described so far. The configuration of the latch mechanism 20 will be described below.

<Configuration of Latch Mechanism (First Embodiment)>
FIG. 5 is a perspective view showing a configuration of the latch mechanism 20 according to the first embodiment.

As shown in FIG. 5, the latch mechanism 20 according to the first embodiment includes an accommodation member 21, a pin 22, a first latch member 23, a second latch member 24, a third latch member 25, and an attachment. Force member 26. Further, the latch mechanism 20 is provided at a position in the middle of the wire 50 having the distal end portion 50a and the operation portion 51 on both end sides.

The housing member 21 houses the first latch member 23, the second latch member 24, the third latch member 25, and the biasing member 26. The pin 22 is inserted into the lateral hole portion 25 g (see FIG. 6E) of the third latch member 25, and fixes between the third latch member 25 and the wire 50.

The first latch member 23 has a cylindrical shape in which a through-hole 23b (see FIG. 6A) that is a circular hole is formed at the center, and is fixed to the housing member 21. And the 2nd latch member 24 and the 3rd latch member 25 are arrange | positioned at this penetration part 23b.

The first body portion 25a (see FIG. 6E) of the third latch member 25 is inserted into and supported by the second latch member 24 having a cylindrical shape. The third latch member 25 is formed with a through hole 25c (see FIG. 6E) that is a circular hole in the center, and the wire 50 is inserted through the through hole 25c. The third latch member 25 is pivotally supported by the wire 50 and is configured to be rotatable around the wire 50.

The biasing member 26 includes a spring portion 26a and a washer 26b, and is disposed between the side surface 21a on the operation portion 51 side of the housing member 21 and the disc portion 25d (see FIG. 6E) of the third latch member 25. The Then, the urging member 26 urges the third latch member 25 in the direction D3 that is the direction facing the distal end portion 50a side in the latch mechanism 20.

In the following description, for example, when the wiring of the wire 50 is assumed to be a river, the distal end portion 50a is upstream, and the operation portion 51 is downstream, the "front end portion 50a side" means the upstream side. The “operation unit 51 side” means the downstream side.

Furthermore, the above-described first latch member 23 is formed with a longitudinal groove 23d extending along the direction D3. A projection 24 c provided on the side surface of the second latch member 24 and a latch portion 25 e provided on the side surface of the third latch member 25 are fitted into the vertical groove portion 23 d.

Here, when the user operates to pull the operation unit 51, the third latch member 25 fixed to the wire 50 by the pin 22 moves in the direction opposite to the direction D3 (that is, the operation unit 51 side in the latch mechanism 20 is Move in the direction D4.

Also, the second latch member 24 supported near the upper surface of the third latch member 25 via the washer 27 is pressed by the third latch member 25 and moves in the direction D4. That is, when the user operates to pull the operation unit 51, the second latch member 24 and the third latch member 25 move in the direction D4.

Here, when the third latch member 25 moves in the direction D4 and the latch portion 25e comes out of the longitudinal groove portion 23d of the first latch member 23, the third latch member 25 rotates in a predetermined rotation direction R1. Then, after the latch portion 25 e has run over the first slope portion 23 e of the first latch member 23, the third latch member 25 that has rotated about ¼ in the rotation direction R <b> 1 is engaged with the first latch member 23.

Thereby, since the third latch member 25 holds the position on the direction D4 side, that is, the operation portion 51 side, the tip portion 50a of the wire 50 can also hold the position on the operation portion 51 side. Therefore, in the clutch mechanism 10 shown above, the connecting member 12 can hold the position on the operation unit 51 side (that is, the position separating from the first gear 11). That is, the second state of the clutch mechanism 10 can be maintained by the latch mechanism 20.

Further, in a state where the latch portion 25e of the third latch member 25 rides on the first slope portion 23e of the first latch member 23 and is locked to the first latch member 23, the user pulls the operation portion 51 again. When operated, the latch portion 25e is released from the state of being locked to the first latch member 23, and the third latch member 25 rotates in the rotation direction R1.

Then, the latch portion 25e of the third latch member 25 that has rotated 1/4 in the rotation direction R1 is fitted into the longitudinal groove portion 23d of the first latch member 23. Here, since the third latch member 25 is urged in the direction D3 by the urging member 26, the third latch member 25 moves in the direction D3 while the latch portion 25e is fitted in the longitudinal groove portion 23d.

Thereby, since the third latch member 25 returns to the position on the direction D3 side shown in FIG. 5, that is, the original position, the tip 50a of the wire 50 can also return to the original position. Therefore, in the clutch mechanism 10 shown above, the connecting member 12 can be returned to the position on the tip end portion 50a side (that is, the position where it engages with the first gear 11).

As described above, when the user repeatedly operates the operation unit 51, the latch mechanism 20 can switch the first state and the second state in the clutch mechanism 10.

Note that the first slope portion 24d and the third slope portion 24f of the second latch member 24 have an inclination angle substantially equal to the first slope portion 23e and the second slope portion 23g of the first latch member 23 described above. The reason will be described later.

FIG. 6E is a perspective view of the third latch member 25 according to the first embodiment. As shown in FIG. 6E, the third latch member 25 has a cylindrical first main body portion 25a and a cylindrical second main body portion 25b, and the first main body portion 25a and the second main body portion 25b are provided. It is configured to be stacked one above the other. Here, the upper first main body portion 25a has a larger diameter than the lower second main body portion 25b.

And the penetration part 25c which is a circular hole is formed so that the center part of the 1st main-body part 25a and the 2nd main-body part 25b may be penetrated. Further, a lateral hole portion 25g penetrating through the through portion 25c and the outer surface of the first main body portion 25a is formed in the upper portion of the first main body portion 25a. The lateral hole portion 25g is shaped so that the pin 22 can be inserted therethrough, and the third latch member 25 and the wire 50 are fixed by inserting the pin 22 through the lateral hole portion 25g. The pin 22 is embedded in a length that does not protrude from the outer surface of the third latch member 25, so that the operation of the second latch member 24 is not hindered.

Furthermore, a disc-shaped disc portion 25d having a diameter larger than that of the first main body portion 25a is provided between the first main body portion 25a and the second main body portion 25b.

Here, on the outer peripheral side surface of the first main body portion 25a, a pair of latch portions 25e, which are protrusions protruding in a bowl shape on the outer peripheral side and extending from the disc portion 25d along the direction D3, are provided. The pair of latch portions 25e are formed at equal intervals in the circumferential direction of the first main body portion 25a.

Furthermore, a slope portion 25f is provided at the end of the latch portion 25e on the direction D3 side. The inclined surface portion 25f is configured such that the position of the surface is directed toward the direction D3 as it proceeds in the rotation direction R1. The slope portion 25f is substantially the same as the first slope portion 24d and the third slope portion 24f of the second latch member 24 (that is, both the first slope portion 23e and the second slope portion 23g of the first latch member 23). Have equal inclination angles.

Here, as shown in FIG. 5, the first body portion 25 a of the third latch member 25 is inserted into the through portion 24 b of the second latch member 24, and the second latch member 24, the third latch member 25, Is inserted through the through portion 23 b of the first latch member 23.

Further, when the clutch mechanism 10 is in the first state, as shown in FIG. 5, the latch mechanism 20 includes both the protrusion 24 c of the second latch member 24 and the latch portion 25 e of the third latch member 25. This is a state in which the third latch member 25 is disposed on the direction D3 side by being fitted into the vertical groove portion 23d of the first latch member 23. In this state, the slope portion 25 f provided on the third latch member 25 is in contact with the first slope portion 24 d provided on the bottom surface of the second latch member 24.

In the latch mechanism 20 in such a state, when the user pulls the operation unit 51, a force in the direction D4 is applied to the third latch member 25, and this force becomes a force that resists the urging force of the urging member 26. As described above, the second latch member 24 and the third latch member 25 move in the direction D4.

Then, the latch portion 25e of the third latch member 25 comes out of the vertical groove portion 23d of the first latch member 23. Further, the first slope portion 23 e provided on the bottom surface of the first latch member 23 and the first slope portion 24 d provided on the bottom surface of the second latch member 24 are adjacent to each other.

Here, since the first slope part 23e of the first latch member 23 and the first slope part 24d of the second latch member 24 have substantially the same slope angle, the first slope part 23e and the first slope part 24d are It will be almost flush.

Further, the slope portion 25f provided in the latch portion 25e has an inclination angle substantially equal to the first slope portion 23e and the first slope portion 24d, and the slope of the first slope portion 23e and the slope of the first slope portion 24d. The slope of the slope portion 25f is configured such that the position is directed toward the direction D3 as it proceeds in the rotation direction R1.

Accordingly, when the external force in the direction D4 from the operation unit 51 is released at this stage, the third latch member 25 is urged in the direction D3 by the urging member 26. When the first slope portion 23e and the first slope portion 24d that are flush with 25f slide, the third latch member 25 rotates in the rotational direction R1.

When the third latch member 25 rotates about ¼ in the rotational direction R1 while the inclined portion 25f of the third latch member 25 slides on the first inclined portion 23e of the first latch member 23, the third latch member The 25 latch portions 25e engage with the wall portion 23f of the first latch member 23. Here, the third latch member 25 is urged in the direction D3 by the urging member 26, and the wall portion 23f is configured to face the rotation direction R1. Locked to the wall 23f.

Thereby, since the third latch member 25 holds the position on the direction D4 side, that is, the operation portion 51 side, the tip portion 50a of the wire 50 can also hold the position on the operation portion 51 side.

Therefore, in the clutch mechanism 10 shown above, the connecting member 12 can hold the position on the operation unit 51 side (that is, the position separating from the first gear 11). That is, the second state of the clutch mechanism 10 can be maintained by the latch mechanism 20.

In the second state, since the mechanical lock by the motor 3 is released, the user can easily open and close the shutter manually. That is, a user who opens and closes the shutter after switching the shutter device 100 from electric to manual may operate the operation unit 51 to apply an external force in the predetermined direction D4.

Furthermore, in the first embodiment, since the second state can be maintained by the latch mechanism 20 even after the external force from the operation unit 51 is released, the user can easily maintain the second state. The shutter can be opened and closed manually.

Subsequently, from the state shown in FIG. 5, as described so far, the third latch member 25 moves in the direction D4 and rotates about ¼ in the rotation direction R1, so that the latch portion 25e becomes the first latch member. The operation of each member of the latch mechanism 20 when an external force is applied again in the direction D4 from the operation unit 51 in a state of being locked to the wall portion 23f of 23 will be described.

In the latch mechanism 20 in such a state, when the user pulls the operation unit 51 again, a force in the direction D4 is applied to the third latch member 25, and this force becomes a force against the urging force of the urging member 26. As described above, the second latch member 24 and the third latch member 25 move in the direction D4. At this time, the slope portion 25 f of the third latch member 25 is in contact with the third slope portion 24 f of the second latch member 24.

Then, the latch part 25e of the third latch member 25 rises up the wall part 23f of the first latch member 23 and comes off the wall part 23f. Further, the second slope portion 23 g provided on the bottom surface of the first latch member 23 and the third slope portion 24 f provided on the bottom surface of the second latch member 24 are adjacent to each other.

Here, since the second slope part 23g of the first latch member 23 and the third slope part 24f of the second latch member 24 have substantially the same slope angle, the second slope part 23g and the third slope part 24f are It will be almost flush.

Furthermore, the inclined surface portion 25f provided in the latch portion 25e has an inclination angle substantially equal to the second inclined surface portion 23g and the third inclined surface portion 24f, and the inclined surface of the second inclined surface portion 23g and the inclined surface of the third inclined surface portion 24f. The slope of the slope portion 25f is configured such that the position is directed toward the direction D3 as it proceeds in the rotation direction R1.

Accordingly, when the external force in the direction D4 from the operation unit 51 is released at this stage, the third latch member 25 is urged in the direction D3 by the urging member 26. The third latch member 25 rotates in the rotation direction R1 by sliding the second inclined surface portion 23g and the third inclined surface portion 24f that are flush with each other.

When the third latch member 25 rotates about ¼ in the rotational direction R1 while the inclined portion 25f of the third latch member 25 slides on the second inclined portion 23g of the first latch member 23, the third latch member The 25 latch portions 25e engage with the longitudinal groove portions 23d of the first latch member 23. Here, the third latch member 25 is urged in the direction D3 by the urging member 26, and both the latch portion 25e and the longitudinal groove portion 23d are formed along the direction D3. Therefore, the latch portion 25e is formed in the longitudinal groove portion 23d. The third latch member 25 moves in the direction D <b> 3 while being fitted in.

Thereby, since the third latch member 25 returns to the direction D3 side shown in FIG. 5, that is, the original position, the distal end portion 50a of the wire 50 can also return to the original position.

Therefore, in the clutch mechanism 10, the connecting member 12 can be returned to the position on the tip end 50a side (that is, the first state). That is, when the user repeatedly operates the operation unit 51, the latch mechanism 20 can switch between the first state and the second state in the clutch mechanism 10.

Here, in each member of the latch mechanism 20, as described above, the longitudinal groove portions 23d are formed at equal intervals in the circumferential direction, and the first inclined surface portion 23e, the wall portion 23f, the second inclined surface portion 23g, and the protruding portion. 24c, the 1st slope part 24d, the 2nd slope part 24e, the 3rd slope part 24f, the 4th slope part 24g, and the latch part 25e are each provided in the circumferential direction at equal intervals.

Accordingly, by repeatedly applying and releasing the external force in the direction D4, the third latch member 25 of the latch mechanism 20 switches alternately between the state moved to the direction D3 side and the state moved to the direction D4 side. be able to.

That is, when switching the shutter device 100 from manual to electric, the user only needs to operate the operation unit 51 again and reapply a force in the direction D4 as described above. The third latch member 25 of the latch mechanism 20 moves in the direction D3 and the clutch mechanism 10 returns to the first state only by reapplying a force in the direction D4, so that the driving force from the motor 3 is applied to the rotation mechanism. 2 can be transmitted.

As described above, the drive device 1 according to the first embodiment can release and set the mechanical lock by the motor 3 using the clutch mechanism 10 having a simple configuration. As a result, the mechanical lock can be released and set by the motor 3 while reducing the cost. Therefore, the driving device 1 can switch the shutter device 100 to manual or electric while suppressing cost.

Further, the drive device 1 according to the first embodiment can perform mechanical unlocking or setting using the latch mechanism 20 having a simple configuration. Therefore, in the driving device 1, the shutter device 100 can be switched to manual or electric with a simple configuration.

Further, in the driving device 1 according to the first embodiment, the clutch mechanism 10 and the latch mechanism 20 are configured separately. That is, the connecting member 12 of the clutch mechanism 10 and the latch mechanism 20 are configured separately.

Thereby, according to 1st Embodiment, the clutch mechanism 10 which needs to be arrange | positioned to the gear group 4 can be made compact. Furthermore, according to the first embodiment, since the latch mechanism 20 can be arranged in the empty space of the shutter device 100, the empty space of the shutter device 100 can be effectively used.

As shown in FIG. 10, the second latch member 24 is integrated with the shaft member 16 of the clutch mechanism 10A. The shaft member 16 includes a columnar main body 16a extending along the direction D1 and a columnar shaft 16b extending along a direction perpendicular to the direction D1. The main body portion 16a is formed with a through portion 16c that is a square hole penetrating in a direction perpendicular to the direction D1.

Here, as shown in FIG. 8, the main body portion 16 a of the shaft member 16 is disposed in the vertical hole portion 14 d of the shaft support member 14. Further, the shaft 16 b of the shaft member 16 protrudes outward from the through portion 14 e of the shaft support member 14 and is locked to the bottom surface portion 12 f of the connecting member 12 via the washer 17. Moreover, the front-end | tip part 50a of the wire 50 is latched by the penetration part 16c, and the wire 50 is penetrated by the penetration part 24b (refer FIG. 11C).

Here, when the user operates an operation unit 51 (not shown) connected to the wire 50 and applies a force toward the direction D2 to the shaft member 16, the direction toward the direction D2 is applied to the connecting member 12 locked to the shaft 16b. You can apply power.

And when the force which goes to this direction D2 turns into the force which resists the biasing member 15, the connection member 12 can be moved to the direction D2. Thereby, the clutch mechanism 10A can be switched from the first state to the second state.

Returning to the description of each component of the latch mechanism 20A. The first latch member 23 has a cylindrical shape in which a through-hole 23 b (see FIG. 11A) that is a circular hole is formed at the center, and is fixed to the shaft support member 14. And the 2nd latch member 24 and the 3rd latch member 25 are arrange | positioned at this penetration part 23b.

A projection 24 c provided on the side surface of the second latch member 24 and a latch portion 25 e provided on the side surface of the third latch member 25 are fitted into the vertical groove portion 23 d.

Here, when the user operates to pull the operation unit 51, the shaft member 16 fixed to the wire 50 moves in the direction D2. Thereby, the 2nd latch member 24 comprised integrally with the shaft member 16 also moves to the direction D2.

Furthermore, the third latch member 25 provided on the direction D2 side of the second latch member 24 is pressed by the second latch member 24 and moves in the direction D2. That is, when the user operates to pull the operation unit 51, the second latch member 24 and the third latch member 25 move in the direction D <b> 2 via the shaft member 16.

Here, when the third latch member 25 moves in the direction D2 and the latch portion 25e comes out of the longitudinal groove portion 23d of the first latch member 23, the third latch member 25 rotates in a predetermined rotation direction R1. Then, after the latch portion 25 e has run over the first slope portion 23 e of the first latch member 23, the third latch member 25 that has rotated about 1/8 in the rotation direction R <b> 1 is engaged with the first latch member 23.

Thereby, since the third latch member 25 holds the position on the direction D2 side, that is, the operation portion 51 side, the shaft member 16 can also hold the position on the operation portion 51 side. Therefore, in the clutch mechanism 10 </ b> A shown above, the connecting member 12 can hold the position on the operation unit 51 side (that is, the position separating from the first gear 11). That is, the second state of the clutch mechanism 10A can be held by the latch mechanism 20A.

Further, in a state where the latch portion 25e of the third latch member 25 rides on the first slope portion 23e of the first latch member 23 and is locked to the first latch member 23, the user pulls the operation portion 51 again. When operated, the latch portion 25e is released from the state of being locked to the first latch member 23, and the third latch member 25 rotates in the rotation direction R1.

Then, the latch portion 25e of the third latch member 25 rotated by 1/8 in the rotation direction R1 is fitted into the vertical groove portion 23d of the first latch member 23. Here, since the third latch member 25 is urged in the direction D1 by the urging member 26, the third latch member 25 moves in the direction D1 while the latch portion 25e is fitted in the longitudinal groove portion 23d.

Thereby, since the third latch member 25 returns to the position on the direction D1 side shown in FIG. 10, that is, the original position, the shaft member 16 can also return to the original position. Therefore, in the clutch mechanism 10A shown above, the connecting member 12 can return to the position on the tip end portion 50a side (that is, the position where it engages with the first gear 11).

As described so far, when the user repeatedly operates the operation unit 51, the clutch mechanism 10A can switch between the first state and the second state by the latch mechanism 20A.

FIG. 11E is a perspective view of the third latch member 25 according to the second embodiment. As shown in FIG. 11E, the third latch member 25 has a cylindrical first main body portion 25a. And the penetration part 25c which is a circular hole is formed so that the center part of the 1st main-body part 25a may be penetrated. In addition, a disc-shaped disc portion 25d having a larger diameter than the first main body portion 25a is provided on the end surface on the direction D2 side of the first main body portion 25a.

Here, on the outer peripheral side surface of the first main body portion 25a, there are provided four latch portions 25e which are protrusions protruding in the shape of a bowl on the outer peripheral side and extending from the disc portion 25d along the direction D1. The four latch portions 25e are formed at equal intervals in the circumferential direction of the first main body portion 25a.

Furthermore, a slope portion 25f is provided at the end of the latch portion 25e on the direction D1 side. The slope portion 25f is configured such that the position of the surface is directed toward the direction D1 as it proceeds in the rotation direction R1. The slope portion 25f is similar to the first slope portion 24d and the third slope portion 24f of the second latch member 24 (that is, the first slope portion 23e and the first slope portion 23e of the first latch member 23) as in the first embodiment. The two inclined surfaces 23g) have substantially the same inclination angle.

Here, as shown in FIG. 8, the first body portion 25 a of the third latch member 25 is inserted into the through portion 24 b of the second latch member 24, and the second latch member 24, the third latch member 25, Is inserted through the through portion 23 b of the first latch member 23.

Further, when the clutch mechanism 10A is in the first state, the latch mechanism 20A includes a protrusion 24c of the second latch member 24 and a latch portion 25e of the third latch member 25 as shown in FIG. This is a state where the third latch member 25 is disposed on the direction D1 side by being fitted into the longitudinal groove portion 23d of the first latch member 23. In this state, the slope portion 25 f provided on the third latch member 25 is in contact with the first slope portion 24 d provided on the bottom surface of the second latch member 24.

In the latch mechanism 20 </ b> A in this state, when the user pulls the operation unit 51, a force in the direction D <b> 2 is applied to the shaft member 16, and when this force becomes a force against the urging force of the urging member 26, As described above, the second latch member 24 and the third latch member 25 move in the direction D2 via the shaft member 16.

Then, the latch portion 25e of the third latch member 25 comes out of the vertical groove portion 23d of the first latch member 23. Further, the first slope portion 23 e provided on the bottom surface of the first latch member 23 and the first slope portion 24 d provided on the bottom surface of the second latch member 24 are adjacent to each other.

Here, since the first slope part 23e of the first latch member 23 and the first slope part 24d of the second latch member 24 have substantially the same slope angle, the first slope part 23e and the first slope part 24d are It will be almost flush.

Further, the slope portion 25f provided in the latch portion 25e has an inclination angle substantially equal to the first slope portion 23e and the first slope portion 24d, and the slope of the first slope portion 23e and the slope of the first slope portion 24d. The slope of the slope portion 25f is configured such that the position is directed toward the direction D1 as it proceeds in the rotation direction R1.

Therefore, when the external force in the direction D2 from the operation unit 51 is released at this stage, the third latch member 25 is urged in the direction D1 by the urging member 26. When the first slope portion 23e and the first slope portion 24d that are flush with 25f slide, the third latch member 25 rotates in the rotational direction R1.

When the third latch member 25 rotates about 1/8 in the rotation direction R1 while the inclined portion 25f of the third latch member 25 slides on the first inclined portion 23e of the first latch member 23, the third latch member The 25 latch portions 25e engage with the wall portion 23f of the first latch member 23. Here, the third latch member 25 is urged in the direction D1 by the urging member 26, and the wall portion 23f is configured to face the rotation direction R1. Locked to the wall 23f.

Thereby, since the third latch member 25 holds the position on the direction D2 side, that is, the operation portion 51 side, the shaft member 16 can also hold the position on the operation portion 51 side.

Therefore, in the clutch mechanism 10A shown above, the connecting member 12 can hold the position on the operation unit 51 side (that is, the position separating from the first gear 11). That is, the second state of the clutch mechanism 10A can be held by the latch mechanism 20A.

In the second state, since the mechanical lock by the motor 3 is released, the user can easily open and close the shutter manually. In other words, the user who wants to open and close the shutter after switching the shutter device 100 from electric to manual may operate the operation unit 51 to apply an external force in the predetermined direction D2.

Furthermore, in the second embodiment, since the second state can be maintained by the latch mechanism 20A even after the external force from the operation unit 51 is released, the user can easily maintain the second state. The shutter can be opened and closed manually.

Subsequently, from the state shown in FIG. 10, as described so far, the third latch member 25 moves in the direction D2 and rotates about 1/8 in the rotation direction R1, so that the latch portion 25e becomes the first latch member. The operation of each member of the latch mechanism 20 </ b> A when an external force is applied again in the direction D <b> 2 from the operation unit 51 in the state of being locked to the wall portion 23 f of 23 will be described.

In the latch mechanism 20A in this state, when the user pulls the operation unit 51 again, a force in the direction D2 is applied to the shaft member 16, and the force becomes a force against the urging force of the urging member 26. As described above, the second latch member 24 and the third latch member 25 move in the direction D2 via the shaft member 16. At this time, the slope portion 25 f of the third latch member 25 is in contact with the third slope portion 24 f of the second latch member 24.

Then, the latch part 25e of the third latch member 25 rises up the wall part 23f of the first latch member 23 and comes off the wall part 23f. Further, the second slope portion 23 g provided on the bottom surface of the first latch member 23 and the third slope portion 24 f provided on the bottom surface of the second latch member 24 are adjacent to each other.

Here, since the second slope part 23g of the first latch member 23 and the third slope part 24f of the second latch member 24 have substantially the same slope angle, the second slope part 23g and the third slope part 24f are It will be almost flush.

Furthermore, the inclined surface portion 25f provided in the latch portion 25e has an inclination angle substantially equal to the second inclined surface portion 23g and the third inclined surface portion 24f, and the inclined surface of the second inclined surface portion 23g and the inclined surface of the third inclined surface portion 24f. The slope of the slope portion 25f is configured such that the position is directed toward the direction D1 as it proceeds in the rotation direction R1.

Therefore, when the external force in the direction D2 from the operation unit 51 is released at this stage, the third latch member 25 is urged in the direction D1 by the urging member 26. The third latch member 25 rotates in the rotation direction R1 by sliding the second inclined surface portion 23g and the third inclined surface portion 24f that are flush with each other.

When the third latch member 25 rotates about 1/8 in the rotation direction R1 while the inclined portion 25f of the third latch member 25 slides on the second inclined portion 23g of the first latch member 23, the third latch member The 25 latch portions 25e engage with the longitudinal groove portions 23d of the first latch member 23. Here, the third latch member 25 is urged in the direction D1 by the urging member 26, and both the latch portion 25e and the longitudinal groove portion 23d are formed along the direction D1, so the latch portion 25e is formed in the longitudinal groove portion 23d. The third latch member 25 moves in the direction D <b> 1 while being fitted in.

Thereby, since the third latch member 25 returns to the direction D1 side shown in FIG. 10, that is, the original position, the tip portion 50a of the wire 50 can also return to the original position.

Therefore, in the clutch mechanism 10A, the connecting member 12 can return to the position on the tip end 50a side (that is, the first state).

A force is applied to the drawer member 42 in the direction D5. Therefore, the drawing member 42 moves in the direction D5 by the force in the direction D5, and the state where the drawing member 42 is locked to the clutch holding member 43 is released.

Thereby, since the drawing member 42 returns to the position on the direction D5 side, that is, the original position, the leading end portion 50a of the wire 50 can also return to the original position. Therefore, in the clutch mechanism 10B described above, the connecting member 12 can be returned to the position on the direction D1 side (that is, the position where it engages with the first gear 11).
