ABSTRACT:
A wheel bearing apparatus provided with a wheel rotational speed detector which has a simplified L-shape and is constituted by a detector end portion and a circuit housing perpendicular to the detector end portion. The detector end portion contains a sensor in opposition to a detected member fixed to a rotating inside member of the wheel bearing and is embedded in an outside member of the wheel bearing, while the circuit housing contains a circuit for processing a signal input from the sensor and is mounted on an outside surface of the outside member in parallel with the axial direction of the outside member so that the circuit housing is inside in the radial direction of the outside surface of a flange provided for the inside member.
