PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor which is capable of compactly mounting the sensor for detecting load on a vehicle, sensing the load on a wheel, and reducing cost during mass production. SOLUTION: The wheel bearing in which a double-row roller 3 is intervened between the external member 1 and the internal member 2, is provided with the sensor unit 21. The sensor unit 21 is composed of the sensor fixing member 22 fixed on the internal peripheral surface of the external member 1 of the stationary side member, and the plurality of strain sensors 23 for measuring the strain of the sensor fixing member 22. The sensor fixing member 22 is provided with at least two contacts and fixing parts 22a and 22b to the external member 1, between the adjacent contacts and fixing parts at least one notch part 22c is provided, wherein the strain sensor 23 is arranged in the notch part 22c. Furthermore, if the internal member 2 is the stationary side member, the fixing member 22 is fixed on the internal member 2. COPYRIGHT: (C)2007,JPO&INPIT
