In the present embodiment, the push portion 343 is configured to move inside the opening 345 when bending forward with the connecting portion 344 as a fulcrum.

Hereinafter, in explaining the operation of the elastic piece 34A of the present embodiment, first, as a comparative example, the configuration and operation of the elastic piece 34 of the first embodiment will be described. In the elastic piece 34, as shown in FIG. 18, the working piece 341 is configured to be flexible between a position where the corresponding switch 511 is pressed and a position away from the corresponding switch 511 with the first end 340 as a fulcrum. Has been done. That is, the elastic piece 34 can bend only with the first end 340 as a fulcrum.

FIG. 19A shows the state of the elastic piece 34 before the handle 7 is pushed in. When the handle 7 is pushed in this state, the working piece 341 is pushed by the handle 7 and bends backward with the first end 340 as a fulcrum. Then, as shown in FIG. 19B, the corresponding switch 511 is operated by the rear end of the working piece 341 pressing the corresponding switch 511.

Here, the handle 7 may be further pushed from the state shown in FIG. 19B. In this case, the action piece 341 tries to move further backward with the first end 340 as a fulcrum by being pushed by the handle 7. Then, if the corresponding switch 511 does not have a mechanism for absorbing the stroke of the elastic piece 34, that is, if the corresponding switch 511 does not allow overtravel, the corresponding switch 511 may be overloaded. be.

Next, the operation of the elastic piece 34A of the present embodiment will be described. FIG. 17A shows the state of the elastic piece 34A before the handle 7 is pushed in. When the handle 7 is pushed in this state, the acting portion 342 is pushed by the handle 7 and bends backward with the first end 340 as a fulcrum. Then, as shown in FIG. 17B, the push portion 343 (protrusion portion 346) contacts the corresponding switch 511, and the corresponding switch 511 is pressed to operate the corresponding switch 511. Here, when the handle 7 is further pushed in from the state of FIG. 17B, as shown in FIG. 17C, the push portion 343 bends forward with the connecting portion 344 as a fulcrum, so that the push portion 343 is in contact with the switch 511 (FIG. 17C). Move forward from the position shown by the imaginary line). That is, the force acting on the acting portion 342 when the handle 7 is pushed in is absorbed by the bending of the pushing portion 343.

As described above, the elastic piece 34A of the present embodiment can absorb the force acting on the elastic piece 34A by pushing the handle 7 as compared with the elastic piece 34 of the first embodiment. Therefore, in the wiring device 10C of the present embodiment, when the handle 7 is pushed in, even if the corresponding switch 511 does not have a mechanism for absorbing the stroke of the elastic piece 34A, an excessive load is applied to the corresponding switch 511. Is hard to hang. That is, in the wiring device 10C of the present embodiment, the stress applied to the switch 511 by pushing the handle 7 can be reduced, and the life of the switch 511 can be extended.

Further, in the present embodiment, the cover 3 has a stopper 37. Therefore, in the present embodiment, as shown in FIG. 17C, the stopper 37 restricts the rearward movement of the handle 7 by coming into contact with the handle 7. That is, in the wiring device 10C of the present embodiment, since the stopper 37 restricts the excessive pushing of the handle 7, the stress applied to the switch 511 can be further reduced by pushing the handle 7. Of course, even if the cover 3 does not have the stopper 37, it is possible to reduce the stress applied to the switch 511 only by the elastic piece 34A.

<Modification example>
By the way, in the present embodiment, the push portion 343 of the elastic piece 34A has a structure that can bend with the connecting portion 344 at one end in the vertical direction as a fulcrum, that is, a so-called cantilever structure, but may have another structure. .. For example, the elastic piece 34A may have two joints 344. The push portion 343 may have a structure that can be bent while being supported by two connecting portions 344 at both ends in the vertical direction. That is, the push portion 343 may have a structure that can be flexed with the connecting portion 344 as a fulcrum.
