发明名称 TIRE MOLDING DIE
摘要 <P>PROBLEM TO BE SOLVED: To provide a tire molding die to manufacture a pneumatic tire wherein work to take out the tire from a die is not complicated, original performance of the projections is spoiled by suppressing the projections after vulcanizing from becoming non-vulcanized, in the pneumatic tire which has projections to generate turbulent flow. <P>SOLUTION: In the tire molding die which has a side mold for printing a sidewall of a green tire which is the tire before vulcanizing, the side mold includes: a surface forming part which forms a surface of the sidewall of the tire; and a first recess which becomes depressed towards a tire width direction outside from a surface forming part. In the first bottom which is the bottom in the first recess, a second recess which becomes depressed towards outside the tire width direction from the first bottom is formed. In a cross-section in the direction which is orthogonal to the tire width direction and the tire circumferential direction, the area of the second bottom which is the bottom in the second recess is smaller than the area of the opening which opens to the first recess in the second recess. <P>COPYRIGHT: (C)2012,JPO&INPIT
