摘要： There is provided a propeller fan in which a clearance between a rotary vane wheel and a shroud is constant three-dimensionally to improve air blowing efficiency and suppress noise. Furthermore, there is provided a propeller fan in which a span length of the rotary vane wheel with respect to the shroud is varied between a front edge portion and a rear edge portion to improve air blowing efficiency and suppress noise. Still further, there is provided a propeller fan characterized in that chamfering is applied only to a negative pressure face of a circumferential outer edge portion of a vane.
