Abstract: Air guide (10) that rectifies air blown out from an impeller includes a plurality of guide vanes (80) having a circular arc shape. In a cross-sectional shape of each one of flow passages (81) of air guide (10), length B of a straight-line portion in a shaft direction of an inner wall-surface formed by one of guide vanes (80) on an outer peripheral side is small compared with length A of a straight-line portion in a shaft direction of an inner wall-surface formed by one of guide vanes (80) on an inner peripheral side. This provides a uniformed flow velocity distribution inside flow passages (81), resulting in a reduced loss caused by differences in flow velocity.
