<p>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 ring 1 which is fixed to a vehicle body; rotary rings 2 and 3 which are inserted through the fixed ring 1 so as to be rotatable therein; and plural rows of rolling elements 5 which are disposed between the fixed ring and the rotary ring so as to roll. A vehicle-outboard-side end of an annular sensor housing 16 having plural displacement sensors 24 disposed 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 rings 2 and 3 is press-fitted to the inner peripheral surface of the vehicle-inboard-side end of the fixed ring 1. In addition, the displacement sensors 24 are coated by a synthetic resin or a rubber-based material so as to be integrally formed with the sensor housing 16.</p> |
