PROBLEM TO BE SOLVED: To provide a bearing device with a sensor which has a low cost, an accurate mounting of the sensor, excellent in a reliability, and responding easily to the various and different size bearing part. SOLUTION: An encoder 17 of a rotation sensor part 2 is attached to an inner part 4 of the bearing part 1. The sensor 18 is attached in an edge part of an external part 3 via a sensor mounting part 22. The sensor mounting part 22 has a fastening cylinder part 22a fitting to an outer diameter face of the external part 3 and a side plate part 22b positioned by axially contacting with an end face of the external part 3. On the side plate part 22b of the sensor mounting part 22, the opposite plate parts of the inner and outer sides which meet mutually are prepared, then the sensor 18 is attached between the opposite plate parts of the inner and outer sides at clamping state. In this case, at the side plate part 22b of the sensor mounting part 22, a U-shaped recessed plate part 25 swelling outward as a cross section shape around a radial direction is formed. A bottom part of this recessed plate part 25 can be used as a previous opposite plate part of the outer side. The sensor mounting part 22 is made as a doubly accumulated shape of an inner plate 23 and an external plate 24. COPYRIGHT: (C)2005,JPO&NCIPI
