TIRE VULCANIZING MOLD

PROBLEM TO BE SOLVED: To provide a tire vulcanizing mold in which an exhaust hole can be easily formed in place of a conventional vent hole, and in which the exhaust hole can be formed even in a specific narrow range of a tire molding surface. SOLUTION: Many heat-resistant cylindrical bodies 4 are arranged on the tire molding surface 2a of a sector 2 and the tire molding surface 3a of a side plate 3 are arranged in such a manner that axial one-side ends of them are exposed and that the adjacent heat-resistant cylindrical bodies 4 circumscribe each other in a close-packed state; one-side ends of a plurality of heat-resistant columnar bodies 4, which are exposed on the tire molding surfaces 2a and 3a, serve as parts of the tire molding surfaces 2a and 3a, respectively; and the tire molding surface 2a of the sector 2 and the tire molding surface 3a of the side plate 3 communicate with a back surface 2b of the sector 2 and a back surface 3a of the side plate 3 through the exhaust hole 5 which is composed of a gap formed between the adjacent heat-resistant cylindrical bodies 4, respectively.
