Abstract

A centrifugal blower includes a plurality of blades, a shroud, a main plate and a tubular portion. An air flow passage is formed between each adjacent two of the blades. When the blades are rotated, air, which is suctioned from one axial side into a suction port is conducted through the air flow passage and is radially outwardly discharged. The shroud has a cover region, which faces another axial side and is shaped in a convex arcuate form. An axial end part of the tubular portion, which faces the one axial side, has an end surface. The end surface and a second virtual line are parallel to each other, or a distance, which is measured between the end surface and the second virtual line in the axial direction, is progressively increased from a radially inner part to a radially outer part of the end surface.
