Abstract
The electric steering lock device () is provided with a cam () which is arranged to allow forward and reverse rotation inside of a frame (), and a lock member () which, while following a cam surface () of the rotating cam (), is arranged to be movable forward and backward between a locked position at the advancing end and an unlocked position at the retreating end. The cam face () comprises a locking and unlocking segment () for moving the lock member () and a lock release position segment (). A change ratio of a cam lift amount to a rotation angle of the cam () in the lock release position segment () is constructed to be smaller than the change ratio of the can lift amount to the rotational angle of the cam () in the locking and unlocking segment ().
