A plurality of mating tabs are provided on an opening for motor installation use disposed in an end plate of a casing. Along with this, a plurality of mating tabs and support tabs are provided on an outer peripheral end of a flange portion, and the flange portion is rotationally retained on the end plate through combination of these members. A protruding wall portion is disposed on a perimeter of an open portion for motor cooling-air use, and a guide rib of tapered configuration is provided adjacently to this wall portion. At the time of the foregoing rotational retaining, an end portion of a cooling-air passage of the flange portion is guided over this guide rib and mated with the protruding wall portion.
