ABSTRACT:
To provide a vehicle-wheel rolling bearing capable of further improving the reliability of a sensor by preventing a temperature drift.A vehicle-wheel rolling bearing H includes a cylindrical fixed ring1which is fixed to a vehicle body; rotary rings2and3which are inserted through the fixed ring1so as to be rotatable therein; and plural rows of rolling elements5which are disposed between the fixed ring and the rotary ring so as to roll. A vehicle-outboard-side end of an annular sensor housing16having plural displacement sensors24disposed in a circumferential direction thereof so as to detect a gap with respect to the outer peripheral surface of each vehicle-inboard-side end of the rotary rings2and3is press-fitted to the inner peripheral surface of the vehicle-inboard-side end of the fixed ring1. In addition, the displacement sensors24are coated by a synthetic resin or a rubber-based material so as to be integrally formed with the sensor housing16.
