A tire transporter which shuttles between a vulcanizing station 1 in which plural pairs of tire molds are arranged to perform vulcanization and a mold opening/closing station 2 in which the tire mold is opened and the vulcanized tire is taken out from the tire mold. Subsequently, an unvulcanized tire to be vulcanized is inserted into the tire mold and shaped before the tire mold is closed. The tire transporter includes a first railway 4 disposed along the vulcanizing station 1 and the mold opening/closing station 2. A truck is provided and moves along the first railway between a first position P1, set in the mold opening/closing station 2, and second positions P2, set at a plurality of portions in front of the vulcanizing station 1. A second railway 12 is disposed on the truck along a direction orthogonal to the first railway 4. A plurality of third railways 13 are disposed at the third positions P3, which are set at a plurality of portions in the vulcanizing station 1, along a direction orthogonal to the first railway 4. Also, a mold transfer unit 32 is provided and moves along the second and third railways 12 and 13 when one of the third railways 13 and the second railway 12 on the truck 19 are connected to each other.

An improved tire vulcanizing press of the type including an upper frame, a lower frame and side frames by way of which said upper frame and said lower frame are integrally connected to one another, wherein a lower die half is fixedly mounted on the lower frame and an upper die half is fixedly secured to a raising and lowering table adapted to be raised up or lowered by means of a raising and lowering means fixedly attached to the upper frame in such a manner that the upper die half is displaced away from or toward the lower die half is disclosed, wherein the improvement consists in that a working cylinder, a spacer and a distance plate are arranged between the upper frame and the upper die half, said distance plate being adapted to move from the operative position in the vulcanizing press to the inoperative one located outward of the latter and vice versa, whereby vulcanizing operation is safely carried out with the minimized die opening in the event of malfunction caused with respect to the working cylinder.
