摘要： To reduce the weight of the wheel support bearing assembly without sacrificing the strength, the wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body structure includes a hub axle (2) formed with a radially outwardly extending hub flange (12). This hub flange (12) has an inner peripheral portion and a remaining wall portion other than the inner peripheral portion, and the remaining wall portion thereof is constituted by a plurality of radially outwardly extending ribs (13) each formed with a bolt insertion hole (14). The hub axle (2) also includes a brake pilot area (16) extending outwardly from an outboard face of the hub flange (12) for guiding an inner peripheral surface of the brake rotor (41). At least the root diameter (D1) of at least an inboard face of each rib (13) is chosen to be equal to or smaller than the outer diameter (D2) of the brake pilot area (16).
