Abstract:
Each of a first rotary blade and a second rotary blade includes a rough surface portion and a smooth surface portion. The rough surface portion has a predetermined width from a blade edge at its circumferential edge portion and has an arithmetical mean roughness of greater than 0.5. The smooth surface portion is provided radially inward of the rough surface portion and has an arithmetical mean roughness less than the arithmetical mean roughness of the rough surface portion.
