SOLUTION: Rotary shaft 13 of a motor 11 having a cut 14 at the forward end is inserted into the rotary shaft through hole in the boss 22 of a fan. Forward end of a fixing bolt 41 then abuts against the cut to secure the fan to the rotary shaft of the motor. The fan is resin molded integrally with a metallic fixing member 26 being inserted into the boss thereof. The metallic fixing member 26 is formed into a tube having a through hole for rotary shaft with a hole for fixing bolt being made in the side wall. Forward end face 36 of the member 26 is exposed along the circumferential edge of the through hole. |
