Abstract:
1. A vehicle push button switch in which a case fixed to a vehicle body or a lid openably and closably attached to the vehicle body is provided with a guide portion for guiding a linear movement of a push button operable by being pushed from outside of a vehicle and supports a switch used to change a switching state in response to a push operation of the push button, wherein the case includes: a first case member fixed to the vehicle body or the lid; a second case member fixed to the first case member and having the guide portion and an opening portion surrounded by the guide portion; and an elastic member having an entire outer peripheral flange portion interposed between the first and second case members in such a way that a center portion of the elastic member faces the opening portion, the push button is connected to the center portion of the elastic member such that an elastic force of the elastic member urges the push button in a return direction, the switch is housed in a housing chamber formed between the first case member and the elastic member and is supported by the first case member such that the switching state is changed in response to bending of the center portion of the elastic member which occurs with the push operation of the push button, and a restricting surface restricting expansion of the elastic member by coming in contact with the elastic member is formed in the inner surface of the second case member, in the peripheral edge of the opening portion, and displacement of the elastic member away from the switch is restricted by the restricting surface, the elastic member having an elastic member main portion which is formed closer to the center portion than the flange portion and covering the switch from a rear side, the elastic member main portion being placed, at a portion thereof remote from the flange portion, in abutment against the restricting surface.
