ABSTRACT:
A steering lock apparatus is composed of: a rotational member having an engagement member; an operating portion positioned on a front side of and connected to the rotational member; a holder for holding the rotational member rotatably in forward and backward directions, and for holding the same rotatably in a rear position; an actuator driven by a signal transmitted by a controller upon detection of the rotational member being operated toward a rear side; and a lock member that is operated by the actuator to be engaged with the engagement member of the rotational member in LOCK position for preventing rotation of the rotational member. The rotational member is held rotatably in a rear position and disabled from moving to a front position when the rotational member is operated to a rear position to release engagement between the engagement member of the rotational member and the lock member.
