<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device reducing variations in gaps of a magnetized body and a sensor in a radial direction while downsizing the device. Ž<P>SOLUTION: A sealing device on the side of a vehicle body axially seals the vehicle body side of the rolling bearing device. The sealing device is mounted on a raceway member 3 on the vehicle body side, and axially has: a step 39 on the vehicle body side; a coupling member 22 in which a magnetic sensor 11 is buried; and a slinger 33 which has the magnetized body 10 fixed on the outer periphery of a first cylinder part 31a, is fixed on an inner ring 17. On the step 39, an elastic sealing member 65 and a second fixed side core bar 35 are provided. The elastic sealing member 65 comes into sliding contact with the slinger 33.
