<p>An electric steering lock device includes an operation relay (RY3) for operating an electric motor (2), a pair of switching relays (RY1,RY2) for switching the rotating direction of the electric motor (2), and diodes (4,5,6) for energizing each relay (RY1,RY2,RY3) connected to a port (3a,3b,3c) of a control unit (3) respectively. A steering shaft is unlocked by providing the operation relay (RY3) in an ON status to allow the electric motor (2) to displace the locking rod in the unlocking direction. The steering shaft is locked by providing the operation relay (RY3) and the pair of switching relays (RY1,RY2) in an ON status respectively to allow the electric motor (2) to displace the steering rod in the locking direction.</p> |
