The rotational sliding cam is locked with a key groove provided on the open end side of the case body free to slide in the axial direction, and has a sliding cam part on one end surface and inserts the shaft in the axial direction of the central part. The rotating cam has a rotating cam part on an end surface facing against the sliding cam part of this rotational sliding cam and inserts the shaft in the axial direction of the central part. The engaging part is provided on the end part of the shaft projected from this rotating cam.
