ABSTRACT:
A force to separate the mold portions for both sides of a tire, created by the pressure of a heating/pressurizing medium introduced into the tire during the vulcanization of the tire, is offset via an upper disk, a segment having protrusions at both ends, and a lower disk. A force in the radial direction to move a tread mold outward is offset via the segment. A component of force in the axial direction (vertical direction) of a radial force, created by the interposition of a sliding inclined surface between the segment and the outer ring is offset via the outer ring, a cover plate, locking claws, the upper disk, and the segment.
