Abstract
There is provided a push button device with which a support plate can be disposed close to a display screen without providing the support plate with a latching mechanism, and which can be easily attached and detached. The invention comprises a push button device that is inserted into the opening of a transparent plate from the front side, and an annular lock plate that is disposed on the back side of the transparent plate and is fitted to the outer peripheral portion of the bottom part of the push button device from the back side. A snap-fit structure that is fixed to the outer peripheral portion of the bottom part by rotating the lock plate is provided to the outer peripheral portion of the bottom part of the push button device and to the inner peripheral portion of the lock plate. The lock plate is configured to have a larger diameter than the opening in the transparent plate, and such that the surface on the support plate side hits the support plate in a state of being fixed to the outer peripheral portion of the bottom part.
