PROBLEM TO BE SOLVED: To remove, in taking out a tire after the vulcanization molding from the bladder, the adhesion between the bladder and the tire by using air and prevent the deformation due to the adhesion. SOLUTION: On the surface of the bladder 10 for molding a raw tire there are formed many grooves 12 whose developed shapes make a V-shape, spiral shape, lattice-like shape or the like. After the completion of the vulcanization molding and before the shrink of the bladder a pressurized air is brown into the grooves 12 of the bladder 10 from the vacuum-destroying air supply pipe 30, and the raw tire 20 is positively released from the surface of the bladder 10.
