<P>PROBLEM TO BE SOLVED: To provide a bearing with a rotation sensor in which a sensor case is combined with a sensor support base from one direction, and in which the sensor case is reusable by preventing an electric wire for magnetic sensor from being broken during creeping. <P>SOLUTION: A sensor support base 40 is formed into an annular body by connecting two division pieces 41, 41 which have the same shape and are located at both diametrical direction-sides of a raceway-side peripheral surface 11, and thereby the sensor support base 40 can be mounted slidably in a shaft rotating direction by axially engaging a peripheral groove part 12 and a projection part 42 each other and by radially positioning the raceway-side peripheral surface 11 with respect to a slide surface 43. A sensor case 30 can be mounted on each division piece 41 by fixation assistance preventing displacement in the opposite direction from an axial mating direction with a spring 100 interposed between a recess 48 of the sensor support base 40 and a leg part 34 of the sensor case 30, and the fixation assistance is released by operating the spring 100 through the inside of the recess 48. <P>COPYRIGHT: (C)2012,JPO&INPIT |
