Abstract

PURPOSE:To prevent the resonance and vibration of a motor and a propeller fan by insert-forming a metal, having a rubber washer stuck to the inner surface so as to come in contact with the step part of an output shaft, at the boss part of the plastic propeller fan fittingly fixed to the output shaft of the motor. CONSTITUTION:A metal 12 with a rubber washer 11 stuck to the inner surface is insert-formed at the boss part of a propeller fan 1. At the time of assembling the propeller fan 1, this boss part is fitted to the output shaft 5 of a motor 4, and then a nut 10 is screwed with a screw part 9 provided being recessed at the tip of the output shaft s so as to fix the propeller fan 1 to the output shaft 5. Then the rubber washer 11 comes in contact with the step part 5a of the output shaft 5, and the metal 12 comes in contact with the nut 10, so that the rubber washer 11 is interposed between the propeller fan 1 and the output shaft 5. The resonance of the propeller fan 1 and motor 4 is thereby prevented, and the number of part items and assembling manhours are reduced.
