Abstract
An axial-flow fan comprises a hub having an axial dimension T.sub.N, and including a planar portion extending in a radial direction. Axial blades connected to the hub, and each axial blade has an axial dimension T.sub.Sch in a vicinity of a radially outermost portion of the hub. The axial dimension T.sub.Sch of each axial blade is greater than the axial dimension T.sub.N of the hub. Each axial blade has a projection U beyond the planar portion of the hub. The projection U extends axially from a leading edge of each axial blade to the planar portion of the hub.
