Abstract A synthetic resin swivel hook (1) having a hook body (11b) and a stopper piece (11c), wherein the stopper piece (11c) includes a base end portion (11c-1) protruded from the base portion; a curved portion (11c-2) formed to be integral with the base end portion (11c-1) and forming substantially C-shape or U-shape protruding toward an inner face of the hook body (11b) and being open outward between the base end portion (11c-1) and the hook body (11b); and a tongue piece portion (11c-3) extending from the curved portion (11c-2) up to an inside fitting face (11b'') at an end of the hook body (11b). The base end portion (11c-1) acts as a protective wall when the curved portion (11c-2) is elastically deformed. Using the above described structure of the curved portion (11c-2) and contraction thereof at the time of molding, from the first, the tongue piece portion (11c-3) is disposed inside of a front end inside fitting face (11b'') of the hook body (11b) upon molding.
