The blade (10) for a propeller constituted by a hub (20) to which the feet (12) are fixed has a leading edge (14) and a trailing edge (15) which is formed by two arcs (152, 153) having respective mean radii of curvature ( rho 2, rho 3) which are different and interconnected without an angular point. These edges are both curved in the downstream direction and define a blade which narrows from the axis to the periphery of the propeller. Application in propellers of motorized fans associated with automobile vehicles.
