Abstract:
1. A wheel support bearing assembly to rotatably support a wheel relative to a vehicle body, comprising: an outer member having an inner peripheral surface formed with axially spaced raceway surfaces; an inner member having an outer peripheral surface formed with axially spaced raceway surfaces in alignment with the respective raceway surfaces of the outer member; circumferentially extending rows of rolling elements interposed between the opposed raceway surfaces; the inner member being made up of a hub axle, having a wheel mounting flange, and an inner race mounted on an outer peripheral surface of an inboard end of the hub axle, and the raceway surfaces being formed in the hub axle and the inner race, respectively; an annular recess formed in the outer peripheral surface of the hub axle adjacent the inboard edge portion of the hub axle; the inboard edge portion of the hub axle being positioned more inboard than the annular recess being plastically deformed radially outwardly to form a plastically deformed portion; and the plastically deformed portion being positioned opposed to a side face of the inner race facing the inboard side so that a surface within the annular recess facing an outboard side engages the side face of the inner race facing the inboard side to thereby prevent a drop-out of the inner race.
