A lock device that locks or unlocks a locking subject includes a lock member moved between a lock position where the lock member locks the locking subject and an unlock position where the lock member unlocks the unlocking subject and a movable transmission member that acts to move the lock member to at least the lock position. A guide mechanism is arranged between the transmission member and the lock member. The guide mechanism includes a sloped lock guide surface. The lock guide surface guides the lock member to the lock position when the transmission member moves in a first direction.
