In a blade cross-sectional view, assuming that a tangent at an end of the outer periphery is defined as LQ, an imaginary line orthogonal to the rotation axis is defined as LO, an angle formed by the tangent (LQ) and the imaginary line (LO) is defined as an outer peripheral end tangent angle (θ), and a position at which an imaginary plane including a position of an intake-side end portion of the bellmouth and a peripheral edge of the blade cross each other is defined as an overlap starting point, the outer peripheral end tangent angle on a trailing edge portion side with respect to a blade cross section including the overlap starting point is set to be smaller than the outer peripheral end tangent angle on a leading edge portion side with respect to the blade cross section including the overlap starting point.
