Propeller fan, blower, outdoor unit

The projection shape of the rotation axis to the plane having a perpendicular front edge 7 of the blade 5 has a Entotsu unit 15 before projecting the fan rotation direction rear, further towards the rear of the fan rotation direction RD projects the trailing edge 9 having an airfoil shape that has a Koentotsu portion 17, the inner circumferential side from the apex P of the front Entotsu portion is advanced in the fan rotation direction than the vertex P, after position radius Rq vertex Q of Entotsu portion is larger than the position radius Rp of the vertex P, position radius Rq vertex Q is greater than the intermediate radius Rm of the radius Ri of the radius Ro and the inner periphery of the outer peripheral edge.
