Abstract: In an operation device for a vehicle ignition switch includes a rotational member for changing the switching mode, an operation knob connected with the rotational member while permitting the rotational operation to a LOCK, ON, OFF positions, etc. a block member capable of displacement between a position for permitting or inhibiting the rotation of the operation knob, and a solenoid having a plunger connected for driving the block member to a position permitting the rotation of the operation knob in accordance with ID authentication, generation of abnormal sounds caused by the vibrations of the vehicle and injuries due to wearing is reliably prevented at the ON position by the holding member that abuts against the plunger of the solenoid 17 so as to inhibit the displacement thereof.
