An operation restricting device includes an operation knob to be turned by a user, a rotor member to rotate integrally with the operation knob, a case member enclosing the rotor member to be rotatable therein, a stopper member being movable along a radial direction of the rotor member in the rotor member, the stopper member restricting a rotation of the rotor member by engaging with a wall part of the case member, a spring for always providing a spring force biasing the stopper member outside the rotor member in the radial direction, a solenoid to retain a plunger by being energized, and a link member rotatably engaging with the plunger. When the solenoid is energized, the turning of the operation knob allows the stopper member to move back into the rotor member against the spring force such that the engaging of the stopper member is released. |
