Therefore, the rigid core 11 is prevented from being damaged. And this function is surely exerted even when there is a large difference in the coefficient of thermal expansion between the rigid core 11 and the vulcanization mold 55.
- the vulcanization mold 55 is opened by the reverse operation, and the rigid core 11 on which the vulcanized tire is mounted is removed.

- the vulcanizing mold 55 is composed of the lower mold 44, the upper mold 49, and the sector-one mold 54.
- the present invention includes only the lower mold and the upper mold. It is also possible to apply to a vulcanization mold. In this case, the lower half of the tread portion of the unvulcanized tire is molded by the lower mold, and the upper half is molded by the upper mold.
- the outer surface of the movable seal 34 before vulcanization is flush with the upper surface and the lower surface of the rigid core 11, but in the present invention, the total amount of the movable seal pushed in is set.
