The support shafts are rotatably fitted into shaft holes, with each of tip ends thereof projecting from an outer surface of each of the opposed wall portions. A plurality of pairs of bosses are provided on the opposed wall portions and located coaxially with the shaft holes to define inlet openings of the shaft holes at sides of inner surfaces of the opposed wall portions and to abut against opposite end faces of the blade bodies. A plurality of pairs of recesses are provided in the opposed wall portions and located coaxially with the shaft holes. These recesses open into outer surfaces of the opposed wall portions to surround inlet openings of the shaft holes at sides of the outer surfaces of the opposed wall portions.
