Abstract
A blower fan includes a hub, a plurality of blades and a ring. The blades are arranged along and extend outwardly from an outer periphery of the hub. The ring is shaped in a circular ring form and couples a distal end portion of each blade. The distal end portion of each blade has a separation limiting structure that limits separation of a flow of air from the blade. Each blade has a shape that directs a flow direction of the air passing through the blade to the separation limiting structure of an adjacent blade which is an adjacent one of the plurality of blades located on a rear side of the blade in a fan rotational direction.
