Claims

[Scope of Claim for Utility Model Registration] A rotatable operating shaft; a disc-shaped rotating member fixed to the operating shaft; and a rotatable member that protrudes through the rotating member and is rotatable toward the tip side of the operating shaft. A rotational force is applied to the attached operating member so that it always rotates in one direction with the intermediate portion as the center of rotation, and the press-contact portion on the one end side presses against the press-contact portion of the outer circumferential arc surface of the rotating member. At least two or more lock grooves formed on one end surface of the operating member located on the side of the fixed member and a protruding surface between the lock grooves; an engaging protrusion that engages with the rotating member; a guide groove formed on one side of the rotating member or the operating member; and a guide groove formed on the rotating member or the operating member on which the guide groove is not formed. A locking mechanism comprising a guide protrusion that is formed and moves within the guide groove.
