That is, the roof panel unit 20 includes the support fitting 1.
The eaves side holding portion 26 of FIG.

The seal member 60 is formed of an elastic member such as rubber and has a length substantially equal to the longitudinal length of the eaves side holding portion 26. Also, the sealing member 60
The fins 62 are attached to the portion that is in close contact with the eaves-side back support 56,
62 are integrally formed. This sealing member 60 is
At the time of assembling the roof panel unit 20, the roof panel unit 20 is previously fitted to the eave-side end 16 </ b> B of the solar panel 16.
When the seal member 60 is fitted into the eave-side holding portion 26 in this state, the fins 62 are brought into close contact with the eave-side back support portion 56. Thereby, the adhesion of the fins 62 is improved, and the waterproofness of the connecting portion between the photovoltaic panel 16 on the ridge side and the support bracket 18 is improved. Although the seal member 60 having the fins 62 is illustrated as an example, the present invention is not limited to this. Any form may be used as long as the seal member 60 has a shape that wraps around the eave-side end 16B.

On the other hand, the ridge-side holding portion 24 is a ridge-side end 16A.
The ridge side surface support portion 44 supporting the surface of the ridge side via a seal member 40 and the ridge side back surface support portion 46 supporting the back side of the ridge side end portion 16A via the seal member 42 via a ridge side connection portion 48. And are formed in a substantially U-shaped cross section.

The seal member 40 is formed of an elastic member such as rubber similarly to the seal member 60, and is formed to have a length substantially equal to the longitudinal length of the ridge side holding portion 24.
The sealing member 40 includes a base 64 formed in a plate shape,
A plurality (three in this example) of fins (fins) 66, 66
, And a buffer portion 68, and front and rear edge portions 65, 65 of a base portion 64 are fitted into hook portions 45 formed on the ridge side surface support portion 44 and mounted on the ridge side surface support portion 44.

The fins 66, 66,...
4 is formed in a direction inclined with respect to the insertion direction in order to allow the insertion in a direction substantially parallel to the plane of FIG. Thereby, when the ridge side end 16A is inserted in the direction of the arrow A toward the fins 66, 66,..., The fins 66, 66 are pressed by the ridge side end 16A and elastically deform in the insertion direction. When the ridge-side end 16A is inserted to the prescribed position shown by the solid line in FIG. 4, the fins 66 are brought into close contact with the surface of the photovoltaic panel 16 by the elastic restoring force of the fins 66. . Thereby, the waterproofness of the connecting portion between the surface of the photovoltaic power generation panel 16 and the support fitting 18 is improved.
When the ridge-side end 16A is inserted beyond the prescribed position, the tip of the ridge-side end 16A collides with the buffer portion 68 of the seal member 40, and the impact force is absorbed. Therefore, the solar panel 16 is hardly damaged.

The seal member 42 includes seal members 60 and 40.
Similarly to the above, it is formed of an elastic member such as rubber, and has a length substantially the same as the longitudinal length of the ridge side holding portion 24. Further, the seal member 42 is formed of a base 70 formed in a plate shape as shown in FIG. 5, a contact portion 72 formed in a hollow shape, and a reinforcing portion 74 in the form of a protrusion. It is fitted in the formed insertion groove 47 and is mounted on the ridge-side back support part 46.

It is a member for sealing the gap 17 between C and 16C, and its width dimension is set to be about twice the width of the gap 17 in consideration of an error in the width of the gap 17. A rib 81 is formed at the center of the lower surface of the seal 80 along the longitudinal direction of the seal 80.

Fins 82, 82 are formed at left and right symmetrical positions on both side surfaces of the rib 81. The fins 82, 82 are elastically deformed and come into contact with both side edges 16C, 16C of the solar panels 16, 16. . Since the ribs 81 are positioned at the center of the width of the gap 17 by the elastic force of the fins 82, the seal portion 80 is positioned at the center of the width of the gap 17. Therefore, the seal portion 80 is not attached to the gap 17 while being shifted, and the gap 17 is not opened.

The fins 84, 84 are formed at symmetrical positions below the rib 81, and are elastically deformed and abut on the back surface of the solar panel 16. Since the sealing portion 80 is brought into close contact with the surface of the photovoltaic panel 16 by the elastic force of the fins 84, 84, the sealing performance is improved.
