End fixing structure of composite wire rod

An end fixing structure of a composite wire rod that is a composite of continuous fiber and resins formed into a stranded wire, the end fixing structure comprising:

• a wedge body that has a cylindrical shape with an enlarging diameter from a front end portion which receives tensile force toward a rear end portion as a large diameter side on a fixed side, wherein an engaged portion is provided on an inner wall surface of the wedge body for engaging with an outer surface of the composite wire rod, the engaged portion having a shape which is a copy of an outer shape of the composite wire rod;
• and
• a sleeve provided on an outer peripheral side of the wedge body and having a conical and hollow inner structure in which a diameter is enlarged toward a rear end portion at the fixed side;
• wherein the inner wall surface of the wedge body is made of a microscopically irregular surface,
• wherein the wedge body comprises a plurality of divided wedge bodies which are divided with respect to each other along a circumferential direction of the wedge body, wherein divided surfaces of the divided wedge bodies face each other with a space therebetween,
• wherein the plurality of divided wedge bodies are provided with a locking section that restricts mutual relative movement of the divided wedge bodies in an axial direction of the composite wire rod, and
• wherein the locking section comprises a projection portion provided in one of the divided wedge bodies facing another one of the divided wedge bodies, and a groove portion provided in said another one of the divided wedge bodies.
