Abstract
An operation device that provides a clicking sensation, with a compact size and excellent durability. The operation device includes an operation member operated by a user. A magnet has a plurality of magnetic poles and is fixed to the operation member. A movable member includes a first magnetic pole portion and a second magnetic pole portion and is pivotally movably arranged on the magnet. When the operation member is operated in a state in which an attractive force is acting between a magnetic pole of the magnet and the first magnetic pole portion, the attractive force acting between them is reduced. Further, by the movement of the movable member, an attractive force comes to act between another magnetic pole of the magnet and the second magnetic pole portion.
