Abstract

A rotation detection device includes an operation member having an annular shape and configured to be rotatable about a rotation center axis; a base member disposed within the operation member; a switch configured to be pressed as the operation member rotates and disposed on the base member such that a rotation direction of the operation member coincides with a pressing direction; and a returning mechanism configured to return the operation member to an initial position by an elastic force. The returning mechanism is provided within the operation member, and is located opposite to the switch with the rotation center axis interposed between the returning mechanism and the switch.
