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 ringwhich is fixed to a vehicle body; rotary ringsandwhich are inserted through the fixed ringso as to be rotatable therein; and plural rows of rolling elementswhich are disposed between the fixed ring and the rotary ring so as to roll. A vehicle-outboard-side end of an annular sensor housinghaving plural displacement sensorsdisposed 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 ringsandis press-fitted to the inner peripheral surface of the vehicle-inboard-side end of the fixed ring. In addition, the displacement sensorsare coated by a synthetic resin or a rubber-based material so as to be integrally formed with the sensor housing
