1. Field of the Invention A tire press comprising a center post vertically movably extended through a center part of a lower ring mechanism and vertically moving an upper ring with respect to a lower ring mechanism , a heater arranged in an outer peripheral position of the center post on the tire inner peripheral side of a green tire held by the lower ring mechanism and the upper ring , heater to apply a heat to the green tire , a first driving mechanism such as a tubular member vertically moving cylinder capable of vertically moving the heater to a suitable height position so as to move the heater to a suitable position independently of vertical movement of the center post , and a second driving mechanism such as a driving motor capable of rotating the heater . By the provision of such a mechanism as described, press molding relative to a green tire can be completed in a sufficiently short period of time.
