Patent ID: 8025494

Claim:
A tire vulcanization apparatus comprising an upper container which moves up and down in a tire vulcanization position, and a lower container which moves between the tire vulcanization position and a shaping position, the lower container is provided with a bladder which is expanded/shrunk by supplying/discharging pressurized fluid from a fluid supplying apparatus, in the shaping position, a green tire is mounted on the lower container, and shaped by supplying pressurized fluid to the bladder and thus expanding the same, and in the tire vulcanization position, the green tire that has been shaped is held between the upper container and the lower container and is vulcanized by supplying pressurized fluid to the bladder, the fluid supplying apparatus is utilized for both supplying pressurized fluid to the bladder in the shaping position and supplying pressurized fluid to the bladder in the tire vulcanization position, a flow channel for supplying/discharging pressurized fluid from the fluid supplying apparatus to the bladder is comprised of a downstream side movable tube which is connected to the bladder and moves accompanied with the movement of the lower container, an upstream side fixed tube which is connected to the fluid supplying apparatus, and a tube for shaping made of a flexible tube to which the fluid supplying apparatus and the bladder are connected, and the upstream side fixed tube is so arranged that the downstream side movable tube is connected via a joint portion in a state that the lower container has moved to the tire vulcanization position, wherein the joint portion is so arranged that the joint portion closes the flow channel in a state that the joint portion is separated into one or more joint parts.
