Abstract
タービン翼（１）を冷却する構造において、高温ガス流路（ＧＰ）に対して凹状に湾曲する第１翼壁（３）と、凸状に湾曲する第２翼壁（５）との間に形成された冷却通路（１７）と、前記冷却通路に面する両壁面上に設けられた複数の主リブ（３１Ａ，３１Ｂ）を格子状に重ねて構成したラティス構造体（２３）とを設け、ラティス構造体（２３）に、隣接する主リブ間に形成されたラティス流路（３５）に突出するように前記主リブ（３１Ａ，３１Ｂ）に一体的に設けられた副リブ（３７Ａ，３７Ｂ）を有し、前記第１翼壁の内壁面に設けられた副リブ（３７Ａ）と前記第２翼壁の内壁面に設けられた副リブ（３７Ｂ）とが互いに重ならない位置に設けられている。
