Abstract

Provided is a propeller fan including a hub having an oval shape in an axial direction , a plurality of blades that extend from the hub, and at least one reinforcement rib that extends from the hub and is formed closer to a leading edge of each of the plurality of blades. Through this configuration, the propeller fan has blowing efficiency and stiffness, and the weight and material cost of the propeller fan can be reduced.
