A wheel support bearing assembly (1) includes a wheel support bearing (2) and a power unit (3). The power unit (3) is that of an outer rotor design in which a stator (18) is located at an outer periphery of the wheel support bearing (2) and a rotor (19) is located radially outward of the stator (18). A radial extension (L2) of the entire power unit (3) is sized to be radially inward of a peripheral section (12b) of a brake rotor (12). An entirety of the power unit (3), excluding a mount part thereof to a hub flange (7), is sized to be situated in an axial range (LI) between the hub flange (7) and a mount surface, on an inboard side of the wheel support bearing (2), with respect to a vehicle body. The rotor (19) includes an outer shell magnetic body (15), which is made from soft magnetic material and forms an outer shell of the power unit (3), and permanent magnets (14) that are provided to the outer shell magnetic body (15).
