PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor capable of accurately detecting a load applied to a wheel without being influenced by a hysteresis. SOLUTION: The wheel bearing comprises an outer member 1 having double-row rolling surfaces 3 formed on the inner periphery; an inner member 2 having rolling surfaces 4 formed on the outer periphery to oppose to the rolling surfaces 3; and double-row rolling elements 5 interposed between the opposing rolling surfaces 3, 4 of the both members 1, 2. A thick part 1b which is a partially thick portion is provided in part of a fixation side member out of the outer member 1 and the inner member 2. A sensor unit 19 is provided on the outer diameter surface of the fixation side member. The sensor unit 19 has a distortion generating member 20 having two or more contact fixation parts and a sensor 21 mounted to the distortion generating member 20 and detecting distortion of the distortion generating member 20. The sensor unit 19 is fixed to the outer diameter surface of the fixation side member by the contact fixation parts of the distortion generating member 20. COPYRIGHT: (C)2009,JPO&INPIT
