Abstract

The invention provides an impeller capable of reducing the noise due to turbulence vortexes produced in the vicinity of the main plate of the impeller, and provides a low-noise multiblade blower. A multiblade blower (40) consists mainly of an impeller (43), a casing (11) covering the impeller, and a motor (14) for rotating the impeller. The impeller comprises a plurality of blades (33) fixed in the outer peripheral edge of a main plate (61) in the form of a circular plate, the blades being connected together at their other ends by an annular side plate (62).
