An impeller (3) of a multiblade blower includes a plurality of centrifugal blades (11). An intermediate support (16), which is positioned between a main plate (10) and an air inlet (6) and supported by a drive shaft, is arranged in an internal space of the centrifugal blades. The plurality of centrifugal blades are held by the intermediate support as well as being held by the main plate. A blade inlet angle in a region of each of the plurality of centrifugal blades on a downstream side with respect to the intermediate support is set larger than a blade inlet angle in a region of each of the plurality of centrifugal blades on an upstream side with respect to the intermediate support. |
