Patent ID: 8002519

Claim:
A blower comprising an axial flow impeller, a fan motor positioned on a suction side of the axial flow impeller, and a motor stay supporting the fan motor, wherein the motor stay is substantially formed to have a linear shape and a rectangular cross-section and attached in parallel to a rotating surface of the axial flow impeller, the blower comprising an impeller blade front edge of the axial flow impeller that is positioned in a first region which is closer to the motor stay than a second region in which an air flow turbulence in a wake flow of the motor stay is expanded, and in the first region a range of the air flow turbulence is narrower than the second region, and wherein values L and W are set to a range satisfying 0.5<L/W<2.5, in which an interval between the motor stay and the impeller blade front edge of the axial flow impeller is represented by L, and a width of the motor stay is represented by W.
