发明名称 Swivel snap hook of synthetic resin
摘要 In a swivel snap hook having a hook body and a stopper piece, a protrusion, which is molded integrally with a front-end inside engaging face or a front-end outside engaging face of the hook body or the stopper piece, is provided so as to have a minute protruding height and be protruded toward a mating engaging face. Further, a minute portion at a tip end of the protrusion is molded integrally with the mating engaging face. Consequently, the swivel snap hook can be molded such that the front-end outside engaging face of the stopper piece is closed to the front-end inside engaging face of the hook body. Therefore, in the swivel snap hook, a length and a depth of the hook body thereof can be set as the conventional ones, while it can be molded in a state that the front-end outside engaging face of the stopper piece is kept in contact with the front-end inside engaging face of the hook body.
