On the contrary, when the pressure applied to the operating portion 12 is stopped, the operating portion 12 can slide upward to a position where the claw portion 18 ′ hits the upper end of the locking hole 15 and locks.

  As a result, the protrusion 18 is prevented from coming off the locking hole 15 by the claw portion 18 ′, and a stroke for pressing the push button 202 of the wireless push button type slave unit 200 is inserted into the locking hole 15. It can be obtained by the movable range of the protruding portion 16 formed.

  In addition, in the configuration of FIG. 5, the length of the protruding portion 16 that is inserted into the locking hole 15 (the length that protrudes below the bottom side lower end 20a of the supported portion 20 ′) is smaller than that of the example of FIGS. Also, a claw portion 18 ′ is provided at a position further away from the tip of the protruding portion 16 in the root direction. Therefore, after the operation portion 12 is mounted on the base portion 11, if the protruding portions 16 penetrating downward from the locking holes 15 are located at positions opposite to each other and are pinched by fingers and bent inward, The operation portion 12 can be easily removed from the base portion 11 by releasing the stopped state.

  Even when the claw portion 18 is provided inside the projecting portion 16 as in the first embodiment, the projecting portion 16 is increased by increasing the length from the claw portion 18 to the tip of the projecting portion 16. It is possible to provide the claw portion 18 at a position distant from the tip end in the root direction. That is, if the protrusions 16 are configured to be longer than the claws 18 while the claws 18 are provided in the positions shown in FIG. By bending it to, the operating portion 12 can be easily removed from the base portion 11 by releasing the locked state.

  Further, when the claw portion 18 ′ is in contact with the upper end of the locking hole 15, that is, when the operation portion 12 is slid to the highest position, the projection portion 19 contacts the push button 202 of the wireless push button type slave device 200. So that it is not pressed down, and the distance between the claw portion 18 ′ and the bottom side lower end 20 a of the supported portion 20 is determined by the stroke amount of the push button 202 of the wireless push button type slave unit 200. Can be approximately the same as. With this configuration, the protrusion portion 19 provided on the inner surface of the operation portion 12 is always in contact with the push button 202 of the wireless push button type slave device 200, and the operation portion 12 is the same amount as the stroke amount of the push button 202. Can be slidable, so that the pressing on the operation portion 12 can be transmitted to the push button 202 without waste.

  Further, in the above embodiment, an example in which the four locking holes 15 and the four protruding portions 16 are provided has been described, but the present invention is not limited to this. For example, two locking holes 15 and two projecting portions 16 may be provided at positions facing each other.

  Further, in the above-described embodiment, a configuration is provided in which the plurality of locking holes 15 are provided on the circumference of the side wall forming the second support portion 14 and the projecting portion 16 is provided on the circumference of the supported portions 20 and 20 ′.
