ABSTRACT:
An electrically-operated steering lock device includes a protrusion blocking mechanism that blocks protrusion of a lock shaft of a solenoid or the like, and is arranged to prevent malfunctions of the protrusion blocking mechanism even if current is passed through the protrusion blocking mechanism during running of the vehicle. A lock shaft is movable between a protrusion position where a steering shaft is locked and a retracted position where the steering shaft is unlocked, and a lock shaft moving mechanism is coupled to an electric motor and serves to move the lock shaft. The protrusion blocking mechanism is electrically driven and, when the lock shaft is placed at a retracted position, engages with an engagement portion formed in the lock shaft to block protrusion of the lock shaft. A holding device holds the protrusion blocking mechanism in a position where protrusion of the lock shaft is blocked.
