Zusammenfassung:	PROBLEM TO BE SOLVED: To surely close a lid even if a hook part and a permanent magnet are not disposed. SOLUTION: A first cylindrical cam 3 so formed that one end face constitutes a cam face 32 with one or more ridges 32a is slidably disposed within a first cylindrical case 2 with a first spring 4 between them. A second cylindrical cam 6 so formed that its end face opposite to the cam face 32 of the first cylindrical cam 3 constitutes a cam face 61 with one or more ridges 61a is installed via a second spring 7 in such a way as to be slidable about a shaft member 5 journalled to the first cylindrical cam 3 at one end. A third cylindrical cam 9 so formed that its end face opposite to the cam face 32 of the first cylindrical cam 3 constitutes a cam face 91 with one or more ridges 91a is provided inside a second cylindrical case 8 to which the other end of the shaft member 5 can be journalled and in which the second cylindrical cam 6 can be disposed in such a way as to be relatively slidable in its longitudinal direction.
