Abstract:
A steering lock system, comprising:an operation section to be manually operated;an actuator section separated from the operation section for locking/unlocking a steering shaft according to an actuation of the operation section, the actuator section including:a lock member moveable between a lock position where the lock member locks the steering shaft and an unlock position where the lock member unlocks the steering shaft;a first biasing mechanism to bias the lock member toward the lock position;an electric actuator controlled according to the actuation of the operation section;a lock control mechanism having at least an actuation member, a spring receiving member, and a second biasing mechanism, the actuation member being moved back and forth by the electric actuator, the spring receiving member being disposed within the actuation member, the second biasing mechanism being disposed within the actuation member and the spring receiving member to bias the lock member toward the unlock position, and the lock control mechanism causing the lock member to lock/unlock in accordance with the back-and-forth movement of the actuation member,wherein the lock control mechanism stores the spring force of the second biasing mechanism while absorbing displacement of the actuation member when the electric actuator is actuated to effect an unlocking operation while the lock member undergoes handle torque.
