ABSTRACT:
A small click generating member is mounted on a yoke, and a large click generating member is rotatably mounted on an operating shaft. A plunger case is relatively rotatably mounted on the operating shaft, and large and small click pieces are mounted on the plunger case. An electromagnet is mounted on the yoke, and a plunger magnetic body attractable to the electromagnet is mounted on the plunger case. A magnet is mounted to cover the yoke. By changing over the supply of electricity to the electromagnet among a non-electricity-supply state, a backward connection electricity supply state and a forward connection electricity supply state, a generated coil magnetic field and a magnetic field of the magnet are applied in a cooperative manner, a magnetic circuit generated in the yoke can be changed over, and clicks are changed over among large click feeling, small click feeling and a fixed state.
