Abstract:
1. An operation device for a vehicle ignition switch including an ignition switch ( 12 ) for changing a switching mode in accordance with rotation of a rotational member ( 18 ), an operation knob ( 15 ) connected with the rotational member ( 12 ) and capable of rotational operation to a plurality of rotational positions including an ON position, a block member ( 56 ) capable of displacement between a position for permitting the rotation of the operation knob ( 15 ) and a position for inhibiting the rotation of the operation knob ( 15 ), and a solenoid ( 17 ) having a plunger ( 53 ) connected with the block member ( 56 ) and driving the block member ( 56 ) to a position permitting the rotation of the operation knob ( 15 ) in accordance with current supply by ID authentification, in which the device includes a holding member ( 68 ) for holding the plunger ( 53 ) of the solenoid ( 17 ) at the operation of the operation knob ( 15 ) to the ON position so as to inhibit the displacement thereof after ID authentification, wherein the holding member ( 68 ) has a rotational body that rotates along with the rotational operation of the operation knob ( 15 ), and an abutting portion provided integrally with the rotational body and capable of abutting against the plunger ( 53 ) of the solenoid ( 17 )so as to inhibit axial displacement thereof.
