Abstract
A tire vulcanization mold includes an elongated exhaust groove open to a tire molding surface, a plate-like blade inserted in the exhaust groove leaving a small gap between the blade and groove defining surfaces, and an exhaust hole connecting the exhaust groove and mold exterior. The exhaust groove has a length reduced partway in a mold depth direction, and includes upper and shorter lower groove portions positioned on mold surface and back surface sides, respectively, of the mold. The upper groove portion thickness is greater than the blade thickness, and the lower groove portion thickness is less than or equal to the blade thickness. The blade includes a communicating portion connecting the upper and lower groove portions, and abuts against portions of the mold defining a bottom surface of the upper groove portion and edge surfaces of both sides in a thickness direction of the lower groove portion.
