PROBLEM TO BE SOLVED: To provide a tire vulcanizing apparatus capable of obtaining a good pneumatie tire even if an installation space is utilized efficiently. SOLUTION: The tire vulcanizing apparatus 10 has four lower molds 22A-22D, four sub-center posts 26A-26D respectively inserted in the lower molds 22A-22D, four arms for supporting the sub-center posts 26A-26D and one center post lower half part 26 for supporting four arms. By this constitution, the sub-center posts 26A-26D are retracted in the same quantity at the same time. Accordingly, even if a plurality of pneumatic tires are vulcanized and molded at the same time by one tire vulcanizing apparatus 10, the irregularity between the molded pneumatic tires can be reduced markedly. That is, the tire vulcanizing apparatus capable of obtaining the good pneumatic tire even if an installation space is efficiently utilized is realized. COPYRIGHT: (C)2004,JPO&NCIPI |
