Abstract

A lock device locks a locking subject and includes a lock member moved between a lock position for locking the locking subject and an unlock position for unlocking the locking subject. A first urging member urges the lock member to the lock position. A switching member moves between a first position where the switch member fixes the lock member at the lock position and a second position where the switch member permits the lock member to unlock the locking subject. A first actuator drives the switching member. A position detector is arranged in a power supply line connected to the first actuator. The position detector detects whether the lock member has been moved from the unlock position to the lock position subject and permits the supply of power to the first actuator when detecting the movement.
