PROBLEM TO BE SOLVED: To provide a hook structure of a recycle hanger wherein used PET bottles can be reutilized as a hook part thereof, contributing to volume reduction of refuse, the hook part itself can also be reutilized, polymerization rate is high, polymerization degree is high, strength can be increased, necessary strength and tenacity can be obtained, simple construction can be provided, relatively light in weight and high durability is provided. SOLUTION: The hook structure is formed by utilizing a thermoplastic polyester resin materials made from used PET bottles. A thin base material 1 formed into a proper hook-shape, a thin outer peripheral rib 2 which is connected to the outer peripheral edge of the base material 1 and protrudes from the front surface and the rear surface of the material 1, a plurality of thin intermediate ribs 3 which are connected to the inner side and the outer side of the hook so as to protrude from the front side and the rear side of the material 1 are provided so that the front surface area of these members can be made larger.
