A wheel bearing apparatus has an outer member, an inner member and double row rolling elements contained between the outer member and the inner member. A first cap is press-fit into an inboard-side opening of the outer member. The first cap has a cylindrical fitting portion press-fit into an inside fitting surface of the outer member. A bottom portion extends radially inward from the fitting portion to cover the inboard-side end of the inner member. An elastic member is integrally adhered onto an inboard-side outer circumference of the fitting portion of the first cap. The elastic member projects radially outward beyond the outer diameter of the fitting portion. A retracted surface is formed on an inboard-side from the inside fitting surface, via a step portion. The retracted surface has a larger diameter than that of the inside fitting surface. The elastic member press-contacts against the retracted surface while being elastically deformed.
