Abstract

PURPOSE: To reduce the blade pitch sound of a fan by equipping a blade with a different interval or of a different shape and providing a circumferential fam member with uneven weight to correct the unbalanced weight in the circumference caused by the difference of the blade.
CONSTITUTION: At least one among a plurality of blades 2 is given a difference in its equipped interval or its shape. That is, in the illustrated example, blade 2 are equal in their pitches, but only a blade 22 is different from others in its shape. In this construction, as the graph showing sound pressure : second, a waveform with different periods is provided without indicating a single abnormal sound. Besides, the small-sized blade 22 is more thickened than other blades 2 for correcting the caused circumferential unbalancing.
