Abstract: An input device is provided with: an operation member having an operation part, the intended operations thereof being pressing and rotation, and a shaft part that extends from the operation part in the direction of the pressing operation; a support structure having a bearing part that is attached in such a manner as to allow the shaft part to move back and forth along the axis thereof as well as to rotate about said axis; a spring member that provides the operation member with a restoring force against pressing operations; a pressing operation detecting switch that outputs a signal corresponding to the displacement of the operation member that occurs due to a pressing operation; and a rotation operation detecting mechanism that outputs a signal corresponding to the displacement of the operation member that occurs due to a rotation operation.
