ELECTRIC LOCK DEVICE

摘要

An electric lock device, comprising a lock member (8) having a movable member, a cam plate (5) rotated in an unlocking direction and a locking direction by the driving of a drive source and a cam contact face (10) in contact with the sliding surface (6) of the cam plate (5). The lock member (8) is displaced between a locking position for stopping the movement of the movable member by following up the sliding surface (6) and an unlocking position for allowing the movement of the movable member. The cam profile of the sliding surface (6) is set so that the torque of the cam plate (5) necessary for moving the lock member (8) from the locking position to the unlocking position becomes approximately constant.
