PROBLEM TO BE SOLVED: To provide a bearing with a rotation detecting device having enlarged applicable usage and regions, and high versatility. SOLUTION: In this bearing with rotation detecting device, a magnet 2 is mounted on the rotation center O of an inner ring 21 of a rolling bearing 20, wherein a rotating shaft 10 is pressed into the inner ring 21, and a sensor 3, having a plurality of magnetometric sensor elements facing to the magnet 2 for detecting the rotation angle of the magnet 2 is provided on an outer ring 22 of the rolling bearing 20. A sensor unit 7, having the sensor 3 and a sensor fixing member 6 mounted on the outer ring 22 where the sensor 3 is mounted, is provided separately from the outer ring 22. The sensor unit 7 can be fixed to the outer ring 22, after the rotating shaft 10 is pressed into the inner ring 21. COPYRIGHT: (C)2008,JPO&INPIT
