A wheel bearing apparatus has an outer member, an inner member with an inner ring and double row rolling elements rollably contained between inner raceway surfaces of the inner member and outer raceway surfaces of the outer member. The inner ring is axially immovably secured on the wheel hub by a caulking portion. A thickness of a smaller end surface of the inner ring is larger than the height of a stepped portion of a wheel hub of the inner member. The axial position of the smaller end surface of the inner ring is set within an axial range between an axial position of the outermost-side point of the inner-side rolling elements of the double row rolling elements and an axial position of the groove bottom point of an inner raceway surface of the inner ring.
