PROBLEM TO BE SOLVED: To allow a heating medium to flow so that the amount of heat to be transferred from being changed due to a flow velocity and a flow direction. SOLUTION: A heating medium stored in an inner space B is made to flow to apply the heat quantity to the entire inside of a raw tire 4 for vulcanization. The vulcanizer includes: a blowoff tube 63 which blows the heating medium in the outer periphery direction throughout all the areas of a tire width direction in the inner periphery side of the raw tire; a suction tube 64 which sucks the heating medium in the inner periphery side of the raw tire; a gas passage 69 which connects the blowoff tube communicate with the suction tube; and a gas circulation drive machine 67 which makes the heating medium to flow from the suction tube to the blowoff tube in the gas passage. A blow outlet of the blowoff tube is arranged to blow the heating medium in the outer periphery direction at a first angle crossing the radial direction of the raw tire. In an inlet of the suction tube nearer to the center side of the raw tire than the suction tube, an opening direction is arranged so as to suck the heating medium at a second angle which is opposite to the first angle with respect to the radial direction of the raw tire.
