An operation device includes a support portion, a moving body operated by an operator and movably supported by the support portion, a detection unit that detects movement of the moving body, and contact portions respectively provided on the support portion and the moving body and brought into contact with each other. The contact portion of one of the support portion and the moving body has an elastic region that is first brought into contact with the contact portion of the other when the contact portions are brought into contact with each other and a rigid region provided adjacent to the elastic region and continuously brought into contact with the contact portion of the other following the contact of the elastic region to regulate the movement of the moving body.

A push switch includes: a case including a fixed contact; a movable member, a pushing element, and a support. The movable member includes a movable contact. The movable member is disposed at a location to face the fixed contact and is movable between an ON-position and an OFF-position. The pushing element is disposed at a location to face the movable member and is configured to receive external force to push the movable member. The support has such a property that until a travel distance of the pushing element reaches a first threshold, a load applied from the support to the pushing element increases, and when the travel distance of the pushing element reaches the first threshold, the load applied from the support 6 to the pushing element decreases.
