Abstract
It is an object of the present invention to prevent or suppress the occurrence of a temperature difference between upper and lower portions of a green tire in a vulcanizing process carried out by a tire vulcanizing machine 1 and thereby stabilize the tire quality. The tire vulcanizing machine 1 comprises a tire vulcanizing bladder 20 disposed inside a green tire 4, a jet section 90 for jetting a heating/pressurizing medium to the interior of the bladder 20, a medium supply path for supplying the heating/pressurizing medium to the jet section 90, and a holding section 14 for holding an edge portion of the bladder 20, the edge portion being located on the side close to the medium supply path. Further, there are disposed heat insulators 7, 11, 8 and 6 so as to suppress the transfer of heat from the heating/pressurizing medium jetted from the jet section 90, to a lower edge portion of the green tire 4.
