Abstract
A wheel bearing apparatus has a protecting cover formed from non-magnetic material with a substantially dish-shaped configuration. A cylindrical fitting portion is adapted to be press-fit onto the inner circumference of the inner-side end of the outer member. A disc-shaped shielding portion extends radially inward from the fitting portion, via a radially tapered portion. A bottom portion extends from the shielding portion, via a stepped portion. A flat relief portion is formed between the radially tapered portion and the shielding portion. The relief portion is parallel with the shielding portion. The relief portion is set slightly back from the shielding portion toward the radially tapered portion. An elastic member is integrally adhered to the outer circumference of the radially tapered portion. The elastic member elastically contacts with the inner circumference of the inner-side end of the outer member.
