The lid includes an opening at a location corresponding to the tactile switch. A lower surface of the elastic member is coupled to a surface of the lid. The operation button, when pushed, activates the tactile switch with an elastic member. The operation body, when released from the pushed state, deactivates the tactile switch as a reaction force of the elastic member returns the operation button to an initial position. The switch device includes a projection that supports the operation button. The projection is formed on an upper surface of the elastic member at a location corresponding to the surface of the lid.
