Abstract:
A fan rotor blade (1) is provided with a blade body (10) produced from a composite material of resin and reinforced fiber and having a pressure surface (10a) facing one side of the rotation direction and a suction surface (10b) facing the other side of the rotation direction. This blade body is provided with a sheath (20) which has higher rigidity than the blade body and is affixed to the blade body while covering the vicinity of the front edge, which is located on the upstream side in the direction in which outside air is taken in, of the blade body. The leading end (21b) of the sheath extends from the front edge side to the back edge side of the blade body, and an end of the leading end (21b) is flush with the back edge of the blade body.
