Specifically, the claw portion 31 provided on the piano handle 3 is inserted into the opening provided on the switch body 1. Then, the plate frame 5 is attached to the attachment frame 2 by screwing the screws 7 into the screw holes a of the second attachment body 22. Finally, in step S5, the decorative plate 6 is attached to the plate frame 5. Thus, the switch device A is assembled.

Next, the production of the attachment frame 2 will be described with reference to FIGS.
First, in step S11, the 1st attachment body 21 and the 2nd attachment body 22 are formed by press work from a flat steel plate. Specifically, as shown in FIG. 7, the first attachment body 21 is formed from the first steel plate P1 by pressing, and the second attachment body 22 is formed from the second steel plate P2 by pressing. Here, the first mounting body 21 and the second mounting body 22 are punched and bent into a plurality of steps by a press machine. That is, the shapes of the first attachment body 21 and the second attachment body 22 described above are formed by press working.

  Next, in step S <b> 12, the attachment frame 2 is formed by joining the first attachment body 21 and the second attachment body 22. Specifically, the two joint portions 21d of the first attachment body 21 and the two joint portions 22d of the second attachment body 22 are joined by caulking, respectively. That is, the joining structures of the four joining portions 21d and 22d are joined by the same joining means. More specifically, in a state where the protrusion 22j of the joint 22d is inserted into the opening 21f of the joint 21d, the protrusion 22j is pressed by a caulking pin provided in the press. Then, as shown in FIG. 5, caulking is performed by joining the deformed portion 22k formed in the projection 22j, the first opening 21g of the opening 21f, and the enlarged diameter opening 21j. In the present embodiment, all the protrusions 22j are simultaneously pressed by the caulking pins.

More specifically, the opening 21 f of the first attachment body 21 is inserted into the protrusion 22 j of the second attachment body 22 based on the positioning portion 22 c of the second attachment body 22. And based on the positioning part 22c of the 2nd attachment body 22, alignment with a crimping pin and each projection part 22j is performed. Thus, the mounting frame 2 is manufactured.

According to the mounting frame 2 of the switch device of the present embodiment, the following effects can be achieved.
(1) In the mounting frame 2 of the present embodiment, the mounting frame 2 includes a first mounting body 21 and a second mounting body 22 that are a plurality of divided mounting bodies, and the first mounting body 21 and the first mounting body 21. The 2 attachment body 22 shall be the structure joined by caulking. According to this structure, the yield of an attachment frame can be improved significantly compared with the case where the attachment frame 100 shown in FIG. 9 is comprised with a single member. That is, when the mounting frame 100 is configured by a single member, the space SR of the mounting frame 100 is formed, so that the material corresponding to the space SR becomes a waste material. On the other hand, in the attachment frame 2, the first attachment body 21 and the second attachment body 22 are joined to form a space S <b> 1 of the attachment frame 2. In addition, since the space S1 is not formed, no material (steel plate) is used in the portion corresponding to the space S1, and the material does not become waste. Therefore, compared with the case where the mounting frame 100 shown in FIG. 13 is configured with a single structure, the mounting frame 2 can reduce the amount of waste material for forming the mounting frame 2. Yield can be greatly improved.

  (2) In addition, since the joint portion 21d of the first attachment body 21 and the joint portion 22d of the second attachment body 22 are joined by caulking, the joint portions 21d and 22d are compared with joining by screws, press fitting, and joining by adhesion. The bonding strength between the first attachment body 21 and the second attachment body 22 can be improved. Moreover, compared with the case where the joining parts 21d and 22d are joined by welding, the joining strength can be increased by caulking in the case where the joining parts such as the joining parts 21d and 22d are small.

  (3) In the attachment frame 2 of the present embodiment, the joining means of the two joining portions 21d of the first attachment body 21 and the two joining portions 22d of the second attachment body 22 are the same. According to this configuration, the attachment frame 2 is provided with four joint structures for joining the joint portions 21d and 22d. Since the joining means of these four joint structures are the same, the first attachment body 21 and the first attachment body 21 are provided. The joining work of the 2 attachment bodies 22 can be made the same. Therefore, the joining work of the 1st attachment body 21 and the 2nd attachment body 22 can be performed easily.

  (4) In particular, in the mounting frame 2 of the present embodiment, since the joining means of the four joining structures are performed by caulking, for example, the joining means is different when, for example, joining by caulking and joining by screws are used. Compared with the case, the joining work of the 1st attachment body 21 and the 2nd attachment body 22 can be performed easily.

  (5) The mounting frame 2 of the present embodiment is configured such that the protrusion 22j is provided on the second mounting body 22 and the opening 21f is provided on the first mounting body 21. According to this configuration, in the state in which the protrusion 22j is inserted into the opening 21f, the deformed portion 22k is formed by pressing the protrusion 22j to perform caulking. In addition, a member used for joining the joint portions becomes unnecessary. Therefore, the number of parts can be reduced as compared with caulking using eyelets or rivets which are members used for joining the joints.

  (6) In the attachment frame 2 of the present embodiment, in the depth direction, the joint portion 21d of the first attachment body 21 is disposed on the front side from the joint portion 22d of the second attachment body 22, and the joint portions 21d and 22d are In the depth direction, they are configured to overlap each other. According to this configuration, since the joining portions 21d and 22d overlap each other in the depth direction, the joining direction can be performed in one direction. Therefore, the joining work of the 1st attachment body 21 and the 2nd attachment body 22 can be performed easily.

  (7) In the attachment frame 2 of the present embodiment, since the first attachment body 21 and the second attachment body 22 are all joined by caulking, for example, four joining structures can be simultaneously performed by a press machine. That is, the eight protrusions 22j provided in the four joint structures can be deformed simultaneously. Therefore, the first attachment body 21 and the second attachment body 21 are compared with the joints by screws, adhesion, and welding, which are joining means for joining the joint structures of the first attachment body 21 and the second attachment body 22 individually. While facilitating the joining operation of the attachment body 22, it is possible to reduce the time for the joining operation. In addition, even when two joint structures are caulked at the same time among the four joint structures, the joining work of the first attachment body 21 and the second attachment body 22 is compared with joining by screws, adhesion, and welding. While facilitating simplification, it is possible to reduce the time for the joining operation.

  (8) In the mounting frame 2 of the present embodiment, the surface 22m of the deformed portion 22k of the protrusion 22j of the joint portion 22d of the second mounting body 22 is located behind the surface 21p of the first mounting body 21 in the depth direction. The configuration is arranged. According to this configuration, it is possible to suppress contact between the piano handle 3 and the protruding portion 22j that are disposed in proximity to the surface 21p of the first attachment body 21. Here, when the piano handle and the projection contact, the piano handle is separated from the push button handle of the switch body. As a result, the pressing of the piano handle may be difficult to be transmitted to the push button handle.
