PURPOSE:To mold a resin product and a fitting part provided unitarily with the resin product at the same time on a part other than the surface of a parison, by a method wherein a fitting part molding groove is made to form on a mold surface of a molding tool and a core mold which is advancable and retreatable in the direction of a confronting side wall is provided at least on one side wall part of the fitting part molding groove. CONSTITUTION:When a parison 10 is supplied between molding tools 2, 2 through a supply nozzle 1 and air is fed into a molding hollow part through a blowing needle 12 by clamping the molding tools 2, 2, the parison 10 is bonded to molding surfaces 4, 4 and a fitting part molding groove 14 with pressure. Then molding is made to perform by narrowing a groove width of the fitting part molding groove 14 by making a core mold 16 in a retreating state advance in the direction of a confronting side wall by making a cam 24 of an advancing device 20 turn 90 deg.. Then when resin is cured to some extent, the core mold 16 is made to retreat into a slide hole 18 by making the cam 24 turn up to the original position and when the resin is cured, a resin product is unloaded by breaking the molding tools 2, 2.
