Abstract
A fan includes a hub coupled to a driving shaft of a motor, a plurality of blades installed on the outer circumferential surface of the hub to be spaced from each other at a predetermined interval, and a band connecting free ends of the blades. An axial direction width (W1) between a leading edge and a trailing edge at the free end of each of the blades is greater than a width (W2) of the band.
