A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member, inner member and double row rolling elements rollably contained between the inner and outer raceway surfaces of the inner and outer members. Seals are mounted in annular openings formed between the outer member and the inner member. An annular sensor holder, a steel base, and a magnetic encoder integrally adhered to the base are coupled with the inner and outer members. A slinger is positioned on the inner ring so that an axial gap is formed between the base and the slinger.
