PROBLEM TO BE SOLVED: To provide a bearing for wheels with a sensor capable of compactly mounting a sensor for load detection to a vehicle, sensitively detecting the load exerted on wheels, and reducing costs when produced in large quantities. SOLUTION: A sensor unit 16 is mounted to the bearing for wheels in which double-row rolling elements are interposed between an outer member 1 and an inner member. The sensor unit 16 comprises both a sensor mounting member 17 and a displacement sensor 18 mounted to the sensor mounting member 17. In the case that the outer member 1 is a fixed-side member, the sensor unit 16 is mounted to the outer member 1. The sensor mounting member 17 has contact fixing parts 17a and 17b at least at two locations to the outer member 1, and the displacement sensor 18 is arranged at least at one location between the adjacent contact fixing parts 17a and 17b. In the case that the inner member 2 is the fixed-side member, the sensor mounting member 17 is mounted to the inner member 2. COPYRIGHT: (C)2007,JPO&INPIT
