ABSTRACT:
An apparatus for stretching, loosening, and fixing a wire member includes a grasping member for grasping an end of the wire member, a displacing member for displacing the grasping member so as to stretch/loosen the wire member in the longitudinal direction thereof, a fixing member having a wedge receiving face, and a wedge member disposed axially between the fixing member and the grasping member. The wedge has a wedge face tapering toward the wedge receiving face of the fixing member and is divided circumferentially into a plurality of parts. A pushing member pushes the wedge member toward the wedge receiving face of the fixing member, and a holding member holds the wedge member away from the fixing member when the wire member is stretched/loosened by the displacing member.
