Abstract

In a propeller fan, when an interior angle formed when an inside reference point (Q 1 ), a blade tip portion (71 ), and an outside reference point (Q2) are connected in this order by a straight line is defined as y, a relation 12:Sy/n:Sl 7 holds. When the length along the circumference of an arc formed between a first point (PI) and a midway portion (P4) of a circumcircle (CR) is defined as Ln, a relation 0.4:s.Ln/Lm:SO. 7 holds. When the length of a line connecting the center of the circumcircle (CR) with the blade tip portion (71) is defined as RI and the radius of the circumcircle (CR) is defined as RO, a relation 0.8:SRl/RO:S0.95 holds.
