PROBLEM TO BE SOLVED: To keep a high split precision at a low cost and easily control a clearance dimension between the split pieces. SOLUTION: In a tire vulcanizing molding mold 1 which has an inner circumferential shape corresponding to a surface of a tread portion of the tire and is composed by combining a plurality of split pieces 1A split circumferentially, at least one split piece 1A of a plurality of the split pieces 1A has an approximately round rod-like pin protector 100 projecting from a splitting surface D from the neighboring split piece 1A, and the split piece 1A neighboring to this has a concave groove 102 having an approximately circular arc-shaped cross section mating with the pin protector 100 on the combining surface D with the split piece 1A to be combined.
