Abstract

PURPOSE: To reduce facial vibrations and noises in such a way that the contact area is widened between the impeller and motor shaft by bending an edge portion on the shaft hole in the shroud in the rear of the impeller into a cylindrical form along the motor shaft to form a supporting part.
CONSTITUTION: A supporting part 20 is formed by bending an edge portion on a hole 19, for fitting a motor in a shroud 18 in the rear of an impeller 4, into a cylindrical form along the motor shaft. By doing so, even if the outer peripheral part of the impeller 4 may try to vibrate back and forth when the impeller 4 is turned by the motor, because the supporting part 20 exists at the place where the impeller abuts on the motor shaft, the contact area with the motor is widened and suppressing force to the vibration is increased. In consequence, facial vibration of the impeller 4 becomes less, and to its proportion, noises of the fan are decreased. Besides, the hazard of hitting the impeller to the casing and air guide can be reduced.
