<p><P>PROBLEM TO BE SOLVED: To provide a bearing with a rotation sensor applicable to an outer race rotating bearing for supporting a wheel of a motorcycle or a bicycle with a prime mover by a wheel shaft, and enabling stable sensor output and simplification of a peripheral structure by facilitating laying-around of an electric wire for sensor signal output while reducing dimensional restriction in the axial direction for preventing grease leakage by centrifugal force. <P>SOLUTION: This bearing has an encoder 14 installed in one end part of an outer race 3 forming a rotary side bearing ring and a sensor part 15 installed in an inner race 2 oppositely to this encoder 14. The encoder 14 is formed of core metal 17 having the function as a shield plate for preventing the outflow of sealed grease in the bearing and a detecting object 16 integrated into this core metal 17 and detectable by the sensor part 15. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
