A wheel support bearing assembly includes a wheel support bearing and a power unit. The power unit is that of an outer rotor design in which a stator is located at an outer periphery of the wheel support bearing and a rotor is located radially outward of the stator. A radial extension of the entire power unit is sized to be radially inward of a peripheral section of a brake rotor. An entirety of the power unit, excluding a mount part thereof to a hub flange, is sized to be situated in an axial range between the hub flange and a mount surface, on an inboard side of the wheel support bearing. The rotor includes an outer shell magnetic body, which is made from soft magnetic material and forms an outer shell of the power unit, and permanent magnets that are provided to the outer shell magnetic body.
