Abstract

A wheel bearing apparatus has an outer member, an inner member, and double row rolling elements contained between the outer raceway surfaces and inner raceway surfaces of the outer member and the inner member. A cup-shaped steel protective cover is mounted on the inner-side end of the outer member. The cover fitting portion has a cylindrical portion, a radially reduced portion and an elastic member. The elastic member has an annular projection and a contact lip. When the protective cover is fit into the outer member, the annular projection closely contacts with the fitting surface while elastically deforming and the contact lip elastically contacts the inner-side end of the outer member.
