PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor capable of compactly mounting the sensor on a vehicle and sensitively detecting the load on a wheel and reducing costs in mass-production. SOLUTION: The wheel bearing interposing a plurality of rows of rolling bodies 3 between an external member 1 and internal member 2 mounts a sensor unit 21. The sensor unit 21 is provided with a ring member 21 or sensor-mounting member mounted on an end face of the external member 1 as a fixed side member, and a distortion sensor 23 for measuring distortion of the members. When the internal member 2 is the fixed side member, the ring member 22 or sensor-mounting member is mounted on the internal member 2. COPYRIGHT: (C)2007,JPO&INPIT |
