<P>PROBLEM TO BE SOLVED: To provide an operation restriction mechanism of an ignition switch which is made compact by realizing restriction ranges of different rotating operations using a single actuator. <P>SOLUTION: A solenoid 31 restricts a rotation of a rotor 33 by switching a lock piece 54 between in a fixed state and in a movable state. In the movable state, a first leading end 45a of a slide pin 45 contacts a side surface of a first restrict portion 51 so as to restrict a rotation of the rotor 33 from a LOCK position to an ACC position side. In the fixed state, the first leading end 45a overrides the first restrict portion 51 via an inclined surface 57a of the lock piece 54, thereby allows the rotor 33 to be rotated to the ACC position. When the rotor 33 is allowed to be rotated, in the fixed state, a second leading end 45b protrudes from a pin through hole 44 of the rotor 33 by the rotor 33 being rotated to the LOCK position side. The rotation of the rotor 33 to the LOCK position is restricted by the so protruded second leading end 45b contacting a restriction surface 71b of a lock pin 71. <P>COPYRIGHT: (C)2012,JPO&INPIT |
