The axle is formed integrally with diameter-enlarged first and second inner race portions that are respectively disposed in opposing first and second end portions of the hub shell. Each of the first and second inner race portions is formed with an inner race groove that opens toward a respective one of the first and second end portions of the hub shell. Annular first and second cap members are sleeved on the axle. Each of the first and second cap members has an outer race forming portion that extends into and that is mounted to a respective one of the first and second end portions of the hub shell. The outer race forming portion is formed with an outer race groove that opens toward the inner race groove in a respective one of the first and second inner race portions of the axle. A first ball-bearing unit is confined by the inner and outer race grooves in the first inner race portion and the outer race forming portion of the first cap member. A second ball-bearing unit is confined by the inner and outer race grooves in the second inner race portion and the outer race forming portion of the second cap member.
