1. A push button device being inserted into an opening from a front side, comprising:
a flange portion configured to latch to the opening formed in a support plate; and
an annular lock plate that is disposed on a back side of the support plate, is fitted to an outer peripheral portion of a bottom part of the push button device on the back side of the support plate, and is fixed to the outer peripheral portion of the bottom part by being rotated, and
a connection opening for connecting a flexible wiring to an internal connector on the outer peripheral portion of the bottom part,
wherein a snap-fit structure, which is fixed to the outer peripheral portion of the bottom part by rotating the lock plate, is provided to an inner peripheral portion of the lock plate and the outer peripheral portion of the bottom part,
the lock plate is configured to have a larger diameter than the opening, and such that a surface on a support plate side hits the support plate in a state of being fixed to the outer peripheral portion of the bottom part,
and
the lock plate is configured such that in a state of being fixed to the outer peripheral portion of the bottom part, a reinforcing portion of the flexible wiring connected to the connector is sandwiched by an end surface of the connection opening on a side of the flange portion, and pressed.
