An annular sensor holder () has an axial end () including a protrusion (). The axial end () is fitted in a circumferential groove (), such as a seal groove, of a bearing race () fitted to a stationary member () so that the sensor holder () can slide in the circumferential direction relative to the bearing race (). In this state, the sensor holder () is coupled to the stationary member () by means of a fixing arrangement (). Thus, when the bearing race () creeps, the sensor holder () slides relative to the bearing race () and does not rotate relative to the stationary member (). This prevents breakage of connecting wires. 1. A bearing assembly with a rotation sensor , comprisinga rolling bearing including an inner race and an outer race, an annular sensor holder, and a magnetic sensor supported by the sensor holder,wherein the sensor holder can be fitted to one of the inner and outer races,wherein with the rolling bearing mounted between a stationary member and a rotary member, the sensor holder mounted to the one of the inner and outer races, and a signal from the magnetic sensor entered into an external device through wires extending from the sensor holder to the external device, detection is made by the magnetic sensor and an encoder rotationally fixed to the other of the inner and outer races so as to rotate in unison with the other of the inner and outer races,characterized in that the sensor holder is mounted to the one of the inner and outer races so as to be slidable relative to the one of the inner and outer races in a circumferential direction of the rolling bearing.2. The bearing assembly of claim 1 , wherein the one of the inner and outer races is fitted to the stationary member claim 1 , andwherein the bearing assembly further comprises a fixing arrangement through which the sensor holder is coupled to the stationary member such that when fitting surfaces of the stationary member and the one of the inner and outer races rotate relative to each other, the ...
