<P>PROBLEM TO BE SOLVED: To prevent disconnection at creeping for durability even under the use condition of a bearing with a rotation sensor in which a raceway to which a sensor fixing ring is attached may cause creeping. <P>SOLUTION: A sensor fixing ring 40 is attached to one raceway 10 for free sliding in a shaft rotation direction at a protruding part 44 and a peripheral groove 12. Consequently, under the use condition in which the creeping may be generated, the disconnection of an electric wire 60 is prevented by the whirl-stop of only the raceway 10 which utilizes a bearing external member 70. Sliding surfaces such as both side surfaces of the protruding part 44 of both members 10 and 40, a slip surface 45, a circumferential part 13 and the like, are made of low friction layers formed by performing coat-treatment by a fluorine resin, DLC or the like, otherwise formed of a sub-component 49 of the fluorine resin. Furthermore, the sliding surfaces are provided with passages 103, 112, and 122 for directly supplying oil and grease, thus preventing the wear of the sliding surfaces. <P>COPYRIGHT: (C)2013,JPO&INPIT |
