Abstract

　このタイヤ加硫用ブラダーは、ブラダー本体(５２)の外表面にタイヤ周方向の一方から他方に向かってタイヤ幅方向の一方に延びるように形成され、且つ、第１の所定間隔(Ｌ１)をおいて配置された複数の第１エアー抜き溝(５２ａ)と、タイヤ周方向の一方から他方に向かってタイヤ幅方向の他方に延びるように形成され、且つ、第２の所定間隔(Ｌ２)をおいて配置された複数の第２エアー抜き溝(５２ｂ)とが設けられている。また、第１の所定間隔(Ｌ１)に対して第２の所定間隔(Ｌ２)は１.２倍以上４.５倍以下である。このため、ブラダー本体(５２)の外表面が各エアー抜き溝(５２ａ,５２ｂ)によって複数の領域(ＤＢ)に区画され、各領域(ＤＢ)の頂部(ＴＰ)がタイヤ周方向に向かって凸形状となる。従って、ブラダー本体(５２)とタイヤの内表面との密着が各領域(ＤＢ)の頂部(ＴＰ)を起点として解除され易い。
