A structure for fitting the rotary blade cover includes a thin metal plate having an outer diameter larger than the flange, and fastening members for clamping the inner portion of the cover between the flange and the thin metal plate. Bolt assemblies are provided for fastening the thin metal plate and the cover together at a position outside the flange.
