Abstract
A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member and an inner member. A sensor holder with an embedded wheel speed detecting sensor is mounted on an inner side end of the outer member. A pulser ring has an encoder with circumferential characteristics that alternately and equidistantly change. A metal core is press formed from a steel plate and insert-molded into the sensor holder. A sealing member is integrally bonded to the metal core. A connector for electrically connecting the wheel speed detecting sensor to a harness, connected to an electronic circuit, is mounted at a predetermined position on the circumference of the sensor holder. The connector projects radially outward from the circumference at a predetermined inclined. A recess is formed in the connector. The recess is fit onto an inner side end of the outer member in a manner to cover the inner side end, via a predetermined interface.
