PROBLEM TO BE SOLVED: To provide a mold pressurizing device in a tire vulcanization apparatus which can be inexpensively prepd. by eliminating the conventional seal structure while pressing function to a mold is sufficiently provided. SOLUTION: In a mold pressurizing device 3 provided in a tire vulcanization apparatus for vulcanizing and molding a green tire between dividedly formed molds, a recessed part 30 is formed in a base member 22 for receiving a reaction force of the mold and a tube member 31 being expansively and contractibly formed by inner fluid pressure (air pressure) is fitted in this recessed part 30 to receive the reaction force by the base member through this tube member. |
