PROBLEM TO BE SOLVED: To provide a tire vulcanization mold capable of preventing poor appearance of a tire, a manufacturing method of a pneumatic tire using the same and the pneumatic tire.SOLUTION: There is provided a vulcanization mold 1 for molding a pneumatic tire having a tread part 3 and a side wall part 4. It contains a tread segment 6 and a side wall mold 7 and the tread segment 6 and the side wall part 7 are arranged with capability of contacting and releasing and a tread molded face 6a and a side wall molded face 7s are continued with a split surface 9 by contacting each other during mold fastening when tire vulcanization. At least one of the tread molded face 6s or the side wall molded face 7s contains a first projecting stripe part 10 extruding in a tire side at a position neighboring the split surface 9. The first projecting stripe part 10 is formed from a plurality of first projection 12 extending along a tire circumferential direction via a first gap 11.SELECTED DRAWING: Figure 2
【課題】タイヤの外観不良を抑制しうるタイヤ加硫金型、それを用いた空気入りタイヤの製造方法、及び、空気入りタイヤに関する。【解決手段】トレッド部3とサイドウォール部4とを有する空気入りタイヤを成形するための加硫金型1である。トレッドセグメント6とサイドウォール型7とを含み、トレッドセグメント6とサイドウォール型7とは、接離可能に配されるとともに、タイヤ加硫時の型締時に互いに接触してトレッド成形面6sとサイドウォール成形面7sとを割面9で連続させる。トレッド成形面6s又はサイドウォール成形面7sの少なくとも一方は、割面9に隣接した位置でタイヤ側に突出する第1凸条部10を含む。第1凸条部10は、第1隙間11を介してタイヤ周方向に沿ってのびる複数の第1突起12から形成されている。【選択図】図2
