In the present invention, when a tire is vulcanized, a flange (28a) fixed to either one of a top plate (14) of a split mold and a piston rod (23a) tip end of a split mold opening/closing cylinder (23) is held by operating fingers (26a), which are assembled to the other in such a manner as to be capable of oscillating, in the holding direction by the return force of a spring, by which 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 (32), by which the top plate is separated from the piston rod of the split mold opening/closing cylinder. <IMAGE> |
