ABSTRACT:
An antitheft system for a vehicle has an electrically-driven steering lock device. In the lock device, due to a lock arm, which is formed integrally with a helical gear, being driven to rotate by a motor, a lock stopper and a lock bar are moved toward a steering shaft and are set in a locked state. Usually, locking is released by the lock stopper and the lock bar being moved toward a side opposite the steering shaft due to elastic urging force of a spring. In a case in which the lock bar catches on an engagement groove and the lock stopper cannot be moved only by the urging force of the spring, a cam, which is rotated integrally with the helical gear, pushes the lock stopper upward such that locking is released.
