Reinforcing ribs 72 are formed in a lattice shape on one surface of the support main body 71 that faces the mounting surface 42. The reinforcing rib 72 is continuous with the mounting leg 73 to improve the rigidity of the mounting leg 73.

  The mounting leg portion 73 is erected in the display direction from the support main body portion 71 toward the first circuit board 40. The tip portion of the mounting leg 73 in the standing direction has a plate shape along the mounting surface 42. A spacer insertion hole 79 a and a first placement surface 74 are formed at the distal end portion of the placement leg portion 73.

  The boss portion 77 protrudes from the support body portion 71 toward the second circuit board 80 from the two portions of the body portion 71 in the back direction. The tip portion of the boss portion 77 in the protruding direction has a hemispherical shape. A positioning hole 87 formed in the second circuit board 80 is fitted into the boss portion 77. The second circuit board 80 is positioned with respect to the spacer 70 by fitting the positioning hole 87 to the boss portion 77.

  The second support portion 75 has a columnar shape as a whole, a portion standing in the back direction from the support main body portion 71 toward the second circuit board 80, and the support main body portion 71 to the first circuit board 40.

Yes.

  In the combination meter 100 having the above configuration, an assembly process for sequentially assembling the first circuit board 40, the spacer 70, and the second circuit board 80 to the main body member 51 will be described. In the assembling step, first, the first circuit board 40 is placed on the first support portion 52 from the back surface direction to the display direction from the main body member 51. Next, the spacer 70 is placed on the first circuit board 40. The first circuit board 40 and the spacer 70 are fastened together by the screw 49 and fastened to the main body member 51, thereby being supported by the main body member 51. Next, the second circuit board 80 is placed on the second support portion 75 of the spacer 70 fixed to the main body member 51. Then, the second circuit board 80 is fastened to the spacer 70 by the screw 89 and attached to the spacer 70, thereby being indirectly supported by the main body member 51.

  According to the first embodiment described so far, the main body member 51 is positioned in the back direction with respect to the first circuit board 40 by indirectly supporting the second circuit board 80 by the main body member 51. The two-circuit board 80 may not be directly supported. Therefore, a situation in which the shape of the first circuit board 40 and thus the arrangement of the control circuit unit 60 formed on the board 40 is restricted by the structure that supports the second circuit board 80 can be avoided. Therefore, it is possible to ensure both a high degree of freedom regarding the form of the tell tale 20 and the like and a certainty of fixing the circuit boards 40 and 80.

  In addition, according to the first embodiment, the assembly process of each element 40, 70, 80 can be performed from the back side of the combination meter 100. Therefore, even in the structure in which the spacer 70 and the second circuit board 80 are added, the number of steps for rotating the main body member 51 when the elements 70 and 80 are assembled does not increase. In this way, by securing the assembling property of each element 40, 70, 80, even if the configuration has both the degree of freedom of the form of the tell tale 20 and the certainty of fixing the circuit boards 40, 80, The production efficiency of the combination meter 100 can be maintained high.

  In the first embodiment, since the first accommodation space 73 a is formed between the first circuit board 40 and the support main body 71, the arrangement of the control circuit part 60 on the board 40 is restricted by the spacer 70. Things that are done can be avoided. Therefore, it becomes easier to secure the degree of freedom of the form of each display unit 10, 15, 14, and 20.

  Furthermore, in the first embodiment, since the second accommodation space 75a is formed between the second circuit board 80 and the support main body 71, an effective mounting area of the second circuit board 80 is ensured. Therefore, in the configuration of the control circuit unit 60, it is possible to reduce the portion formed on the first circuit board 40 while increasing the portion formed on the second circuit board 80. As described above, since the arrangement of the plurality of light sources 66 and the like on the first circuit board 40 can be facilitated, the degree of freedom of the form of the tell tale 20 and the like is further easily ensured.

  In the first embodiment, the tell tale 20 corresponds to the “display portion” recited in the claims, the first substrate insertion hole 45 corresponds to the “insertion hole” recited in the claims, and the screw 49 Corresponds to the “fastening member” described in the claims, the main body member 51 corresponds to the “first support member” described in the claims, and the spacer 70 corresponds to the “second member” described in the claims. The support main body 71 corresponds to the “first support main body” and the “second support main body” described in the claims, and the mounting leg 73 corresponds to the “support member”. The first housing space 73a corresponds to the "first space" described in the claims, and the second support portion 75 corresponds to the "second space" described in the claims. The second housing space 75a corresponds to the "second space" described in the claims, Nbi Nation meter 100 corresponds to the "display device" described in the claims.

(Second embodiment)
The second embodiment of the present invention shown in FIG. 6 is a modification of the first embodiment. In the combination meter 200 according to the second embodiment, the spacer 270 holds the second circuit board 280 in a posture in which the plate surface direction of the second circuit board 280 intersects the plate surface direction of the first circuit board 40. I support it. The spacer 270 has a support inclined portion 279 instead of the second support portion 75 (see FIG. 2) of the first embodiment. The support inclined portion 279 has a plate shape along the second circuit board 280 and is erected from the support main body portion 71 in the back direction. A fixed groove 277 and a fixed claw 278 are formed in the support inclined portion 279.

  The fixing groove 277 extends along an intersection line between a plane along the support inclined portion 279 and a plane along the support main body portion 71. Since the width of the fixing groove 277 corresponds to the plate thickness of the second circuit board 280, the second circuit board 280 can be fitted into the fixing groove 277. The fixing claw 278 extends in the plate thickness direction of the support inclined portion 279 and locks the outer edge portion of the mounting surface 282 at the tip portion in the extending direction. With the above-described configuration, the board 280 has the second board support surface 276 formed by the second support part 275 by the assembling process of engaging the second circuit board 280 with the fixing claw 278 while fitting the second circuit board 280 into the fixing groove 277. It is clamped between the fixed claws 278.

  Further, the first board insertion hole 45 is located avoiding the area covered with the second circuit board 280 in the first circuit board 40, that is, the area where the second circuit board 280 is projected in the display direction. Therefore, the screw 49 can be inserted into the first board insertion hole 45 without being obstructed by the second circuit board 280. As described above, the step of supporting the second circuit board 280 on the spacer 270 can be performed before the step of fastening the first circuit board 40 and the spacer 270 to the main body member 51 by the screw 49.

  Even in the second embodiment described so far, indirect support of the second circuit board 280 by the main body member 51 can be realized, so that a high degree of freedom regarding the form of the tell tale 20 and the like and fixing of the circuit boards 40 and 280 are achieved. It is possible to achieve a balance with certainty. In addition, in the second embodiment, the arrangement of the first board insertion holes 45 ensures flexibility in the order of the manufacturing process, thereby allowing the degree of freedom of the form of the tell tale 20 and the like and fixing of the circuit boards 40 and 280. Even in the combination meter 200 that can achieve both reliability and reliability, a decrease in production efficiency can be suppressed.

  Furthermore, according to the spacer 270 of the second embodiment, the degree of freedom of setting is improved in the plate surface direction of the second circuit board 280. Therefore, for example, when the interference body OIF or the like is located in the vicinity of the combination meter 200, even if the external shape of the rear cover 259 in the meter 200 is restricted, the plate surface direction of the second circuit board 280 is in such an external shape. Can respond. With the above configuration, the area of the second circuit board 280 can be expanded even while maintaining the physique of the combination meter 200. Thus, by securing the area of the second circuit board 280, electronic components such as the controller 69 can be mounted on the second circuit board 280. Therefore, in the configuration of the control circuit unit 60, the portion formed on the first circuit board 40 can be reduced while the portion formed on the second circuit board 280 is increased. Therefore, since the arrangement of the light source 66 and the stepper motors 63 and 64 on the first circuit board 40 can be facilitated, the degree of freedom of the form of the tell tale 20 and the like is further easily secured.

  In the second embodiment, the spacer 270 corresponds to the “second support member” recited in the claims, and the support body portion 271 corresponds to the “first support body portion” recited in the claims.

(Other embodiments)
Although a plurality of embodiments according to the present invention have been described above, the present invention is not construed as being limited to the above embodiments, and can be applied to various embodiments and combinations without departing from the gist of the present invention. can do.

  In the above embodiment, the first and second accommodation spaces are formed between each circuit board and the spacer, respectively. However, as long as an effective mounting area of each circuit board can be secured, the spacer may be in close contact with at least one mounting surface of the first circuit board and the second circuit board. In addition, the capacity of each accommodation space may be changed as appropriate in accordance with the physique of the electronic component mounted on each circuit board.

  In the above embodiment, the spacer is fastened to the main body member together with the first circuit board. However, the method of fixing the spacer to the main body member is not limited to the above. For example, the spacer may be fastened to the main body member by a screw separately from the first circuit board. Furthermore, the spacer may be attached to either the first circuit board or the main body member by a so-called snap-fit structure using a claw portion having flexibility like the fixed claw 278 of the second embodiment. . Similarly, the method of fixing the second circuit board to the spacer is not limited to the above, and various fixing methods can be applied as the method of fixing the second circuit board to the spacer.

  In the said embodiment, the spacer was mounted on the said 1st circuit board so that the whole control circuit part formed in the 1st circuit board might be straddled. However, the spacers may be placed on the first circuit board so as to straddle only one minute of the electronic components constituting the control circuit unit as long as the arrangement of the light sources and the stepper motors is not hindered.

  As in the above embodiment, it is desirable that the position where the second support portion is provided in the spacer is closer to the outer edge portion than the central portion of the support main body portion 71. Since the distance between the second support portions can be increased by bringing the second support portions close to the outer edge, the second circuit board can be stably supported by the spacers. Furthermore, it is desirable that the second support portion is disposed so as to be adjacent to the first substrate insertion hole with the mounting leg portion interposed therebetween. By making the structure screwed with the screw close to each other, the structure interposed between the second circuit board and the main body member can be reduced, so that the holding of the second circuit board by the main body member can be further ensured.

  Although two circuit boards are provided in the combination meter of the above embodiment, three or more circuit boards may be provided in the meter. In such a form, spacers that respectively support the second circuit board and the third circuit board may be provided, or one spacer 70 may support both the second and third boards. Furthermore, the size relationship of the area of each circuit board may be changed as appropriate.

  Heretofore, an example has been described in which the present invention is applied to a combination meter including a tell tale or the like as a display unit, thereby reducing restrictions on the arrangement of light sources and ensuring the degree of freedom of the tell tale form. However, according to the present invention, the degree of freedom of the configuration of the pointer instrument section and the multi-display section can be improved by reducing restrictions on the arrangement of the stepper motor and the liquid crystal display.
