PROBLEM TO BE SOLVED: To actualize weight reduction and cost reduction on a bearing device fitted with a rotative speed detector. SOLUTION: This bearing device fitted with a rotative speed detector comprises a pulse generator 8 provided on a rotator-side member and a sensor 12 disposed opposite to a stator-side member, these members being among external members and internal members. The stator-side member is mounted with a holder 6 made of resin with a storage pocket 9 formed therein for a sensor 12. A fixing pin 14 fitting into an engagement groove 13a in the sensor 12 is rotatably inserted through the storage pocket 9. A cutout part 14a is formed in a part of an external surface of the fixing pin 14. The sensor 12 can be inserted/extracted with the cutout part 14a positioned so as to confront the engagement groove 13a of the sensor 12 by rotating the fixing pin 14. COPYRIGHT: (C)2005,JPO&NCIPI
