Abstract
A lock device includes a locking member, a movable member, and a transmission mechanism. The locking member is moved between a lock position at which it locks a locking subject and an unlock position at which it unlocks the locking subject. The transmission mechanism transmits a drive force to the movable member and moves the movable member. A movement state of the movable member is shifted between a relative movement state in which it is moved relative to the locking member and an integral movement state in which it is moved together with the locking member to move the locking member toward the lock or unlock position. The lock device further includes a detector of which an output value varies in accordance with movement of the movable member or the transmission mechanism, and a controller that performs a failure determination based on a change in the output value.
