In addition, the above-mentioned metal fitting has a fastening operation bolt having a rotating operation part at a rear part and a screw part at an intermediate part, is rotatably fastened to a rear part of a base piece at a tip part thereof, and is provided behind a holding piece. A pressing piece into which the thread portion of the operation belt is screwed is disposed, and the operating bolt is rotated on the pressing piece in a direction in which the pressing piece advances, thereby acting on the rear portion of the holding piece to apply the holding piece. An action portion for rotating the tip in a closing direction is provided.
