Abstract
【解決手段】ファン動翼1は、樹脂と強化繊維との複合材料からなり、回転方向の一方の側に臨む圧力面10aおよび回転方向の他方の側に臨む負圧面10bを有する翼体10を備えている。この翼体10の基端には、ファンディスクの嵌合溝に嵌合可能なダブテール11aが設けられている。また、翼体には、当該翼体よりも高剛性であって、外気の取り入れ方向上流側に位置する翼体の前縁部近傍を被覆した状態で当該翼体に固定されるシース20を備える。シースは、翼体の翼根側から先端側へと当該翼体の長手方向に沿って延在するとともに、翼体の翼根側に位置する当該シースの基端部21cが、ダブテール11aまで延在している。
