A wheel bearing apparatus has a cup-shaped cap that is coated by a preserving film and mounted on an outer member. The cap is press-formed from non-magnetic steel sheet. The cap has a cylindrical fitting portion, a disk portion and a bottom portion. The cylindrical fitting portion is press-fit into the inner circumference of the inner-side end of the outer member. The disk portion extends radially inward from the fitting portion and opposes a pulser ring, via a small axial gap. The bottom portion extends from the disk portion, via a bent portion, to cover the inner-side end of the inner member. The rotational speed sensor is arranged opposite the pulser ring, via the disk portion of the cap, where the rotational speed sensor is closely arranged to the pulser ring.
