Abstract

PURPOSE: To remarkably reduce the mechanical burden of a key of a cam locking device so as to facilitate the operation of the cam locking device by using a ball, which is driven by a cam, for locking and unlocking. CONSTITUTION: A receiver plate 500 is fitted so that a through hole of a locker 400 is directed, for example, to a starting position of door-opening. At the time of locking, the locker 400 is passed through the receiver plate 500, and when a key, which is inserted into a hole 10 of an inner cylinder 100, is operated, a cam leg 12 is turned so as to extrude a part of a ball 14 outside of the locker 400, and the ball 14 makes the receiver plate 500 and a sleeve 300 pressure-contact with each other. When the key is drawn from the inner cylinder 100, this condition is maintained, and in the case where the receiver plate 500 is fitted so that the through hole of the locker 400 is directed to the starting position of door-opening, opening of the door is interrupted by the sleeve 300. At the time of unlocking, the key is inserted for operation into the hole 10 of the inner cylinder 100, and the cam crest of the cam leg 12 is escaped from the ball 14.
