Abstract

The fan impeller (2) of this disclosure has a hub and a plurality of blades (4) provided on the periphery of the hub. The blades (4) are each configured such that: in a circumferential cross-section of the hub-side part of the blade (4), the front edge (5) section of the blade (4) is elliptically shaped, the intermediate section of the blade (4) is wing shaped, and the rear edge (6) section of the blade (4) has a constant thickness; and in a circumferential cross-section of the center section of the blade (4), the front edge (5) section is circular arc-shaped, the intermediate section is wing-shaped, and the rear edge (6) section has a constant thickness. As a result, the blowing performance is improved and turbulence noise is reduced. (Figure 4)
