ABSTRACT:
Disclosed is a tire press used for manufacturing a tire, in which a mechanism for clamping a closed mold is simplified. An upper heating unit for heating an upper-half mold has a cylinder structure in which a heating medium receiving member and a movable heat transfer member are provided. By supplying the heating medium to the heating medium receiving member, the upper-half mold can be heated via the movable heat transfer member, and the pressure from (clamping action) can be applied on the upper-half mold by the movable heat transfer member.
