摘要： To provide a cross flow fan that can suppress a reduction in resistance to loss of speed, and that can achieve a reduction in fan input and a reduction in noise. Therefore, a negative pressure surface (132) of each of blades (130) of a cross flow fan (100) has a convex part (161) that bulges toward a counter-rotation direction. In a cross section C perpendicular to a rotation axis (140), the convex part of the blade is located on an inner circumferential side of an outer edge (133) of the blade concerned and on an outer circumferential side of an outermost circle of virtual circles (20) tangent to both the negative pressure surface of the blade concerned and the positive pressure surface of the blade adjacent to the counter-rotational side of the blade concerned. In the cross section C, the convex part and a portion of the negative pressure surface on the inner circumferential side of the convex part are connected by a straight part (162). In the cross section C, the straight part is a tangent to both the convex part and the portion of the negative pressure surface on the inner circumferential side of the convex part.

摘要： A propeller fan according to the present disclosure includes a rotation shaft and a blade (1) rotating around the rotation shaft. At the same position in an axial direction of the rotation shaft, a first locus connecting a leading edge (1a) of the blade (1) and an outer peripheral end (1b) of the blade (1) is tilted with respect to a second locus connecting a center of the rotation shaft and the leading edge (1a) so that the outer peripheral end (1b) side is inclined toward a trailing side. Alternatively, a third locus connecting a root (1c) of the blade (1) and the outer peripheral end (1b) of the blade (1) is tilted with respect to a fourth locus connecting a center of the rotation shaft and the root (1c) so that the outer peripheral end (1b) side is inclined toward the trailing side.
