1. An electronic vehicle anti-theft apparatus for preventing theft of a vehicle, comprising:
- a locking means for selectively locking a movable component that is operated when the vehicle is being driven;
an actuator for moving the locking means; and
a control circuit for controlling the actuator, the control circuit including a first power supply line for supplying the actuator with unlocking current that unlocks the movable component, a second power supply line for supplying the actuator with locking current that locks the movable component and a breaker circuit arranged in the second power supply line for breaking the second power supply line but not the first power supply line when the vehicle is started;
wherein the breaker circuit includes a cooperation member, which moves in cooperation with a switch operated by a user when starting the vehicle, and a movable contact, which is moved in accordance with the cooperation member to selectively break the second power supply line.

Abstract
A steering wheel lock apparatus having high reliability. The steering wheel lock apparatus (1) includes a lock pin (21), which engages a steering wheel (5), a motor (23), which moves the lock pin, and a control circuit (31), which controls the motor. The control circuit includes a power supply line (72b), which provides locking current to the motor for locking the steering wheel. A breaker circuit (61) selectively breaks the power supply line when a user operates an ignition switch knob (81) to start the vehicle.
