PROBLEM TO BE SOLVED: To provide a tire vulcanizing mold which can maintain exhaust performance for a long time by preventing malfunction of a vent plug due to rubber biting, and a method for manufacturing a tire using the tire vulcanizing mold.SOLUTION: A vent plug 2 fitted into an exhaust hole 16 opening in a molding surface 1 includes a cylindrical housing 3 having an exhaust passage 21 therein, a stem 4 inserted into the housing 3 and serving as a valve body opening and closing the exhaust passage 21, and an energizing member 5 energizing the stem 4 toward a cavity 15 so as to open the exhaust passage 21. The stem 4 has a columnar trunk part 41 extending in an axial direction of the housing 3, and a head part 42 closing the exhaust passage 21 by being brought into contact with the inner surface of an opening part 31 of the housing 3. A central axis 3A of the housing 3 is inclined with respect to a normal line NL of the molding surface 1 passing through an opening center 16C of the exhaust hole 16. |
