Abstract
PURPOSE: To provide magnets between the axial extensions of a driving motor and blower blades so that the mutually-facing faces thereof may have one polarity for damping the axial mechanical vibration by means of the reactionay force thereof minimize the probabilities of abnormal vibration and noise.
CONSTITUTION: Permanent magnets 17 and 18 are fastened on the end faces at the both ends of the shaft tube section 11 of blower blades 7, and permanent magnets 16 and 19 on the stage portion 3 and nut 20 as the parts corresponding to said both end portions of a rotary shaft 2, so that the mutually-facing faces of said permanent magnets 16 and 17 on one hand and of said permanent magnets 18 and 19 on the other may have one polarity. Thereby, the axial mechanical vibration of said rotary shaft 2 which vibration is generated due to the high-frequency torque foe example of a driving motor 1 can be absorbed by the reactionary force of said permanent magnets 16 and 17 or 18 and 19 to prevent the transmission thereof to said blower blades 7, and the thrust counter to arrow direction can be absorbed. Therefore, the probabilities of abnormal vibration and noise can be minimized.
