Abstract

In the present invention, when a tire is vulcanized, a flange fixed to either one of a top plate of a split mold and a piston rod tip end of a split mold opening/closing cylinder is held by operating fingers. The fingers are assembled in such a manner to be capable of oscillating in the holding direction by the return force of a spring. The top plate is connected to a piston rod of the split mold opening/closing cylinder. Thereupon, the split mold is opened and closed by the output of the split mold opening/closing cylinder and the vertical movement of a bolster plate. When the split mold is replaced, holding is released by oscillating the fingers by using a finger driving device, by which the top plate is separated from the piston rod of the split mold opening/closing cylinder.
