Abstract
An operation input device includes a coil, an operation part configured to be displaced in an axial direction of the coil by the action of an operation input, a core whose positional relationship with the coil is changed by the displacement of the operation part, a yoke placed outside the coil, and a magnet configured to generate a magnetic flux that flows through the core and the yoke. The coil is configured to output a signal corresponding to the amount of the displacement of the operation part. The operation part is caused to move by an electric current flowing through the coil and the magnetic flux of the magnet.
