The fixing screw is threaded into the connection piece from its back. The fixing screw has a head having such a shape as to be disposed throughout the fixing surfaces in tight contact therewith when the threading is completed and is positioned within the width of the connection piece when the threading is loosened. The attachment hole inclined in a direction opposite to the inclination of the fixing surface is provided on a portion of the case band facing to the bow crotch.
