PROBLEM TO BE SOLVED: To suppress a reduction in the blowing efficiency of a fan housing.SOLUTION: A fan housing (60) stores a propeller fan (50) which blows air in the axial direction of a rotation axis (O). The fan housing (60) includes a housing body (61) which is provided encircling the outer periphery of the propeller fan (50) and in the internal space of which air carried by the propeller fan (50) distributes, and stator blades (62) provided on the inner periphery of the housing body (61) and arranged on the leeward side of the propeller fan (50) for straightening the flow of the air blown out of the propeller fan (50). The stator blades (62) each have a cutout (62a) formed in the rear edge at its outer periphery side.SELECTED DRAWING: Figure 9 |
