PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor wherein a load detecting sensor can be compactly installed in a vehicle in a state of resisting a change of an external environment for consistently detecting a load on a wheel with high sensitivity while reducing cot at mass production. SOLUTION: The wheel bearing comprises an outward member 1 and an inward member 2, and double-row rolling elements 3 laid therebetween. A sensor unit 21 is mounted to a fixed side member out of the outward member 1 and the inward member 2. For example, the fixed side member is the outward member 1. The sensor unit 21 is composed of a sensor mounting member 22, and at least one distortion sensor 23 mounted to the sensor mounting member 22. A cover 90 is provided at the outward member 1 for protecting the sensor unit 21. COPYRIGHT: (C)2008,JPO&INPIT
