<P>PROBLEM TO BE SOLVED: To provide a bearing with a sensor, a pulley using the same, and an electromagnetic clutch capable of reducing or eliminating the disagreement between a center of a belt and a center of the bearing in being used to support an offset-type pulley or the like, elongating service life of the bearing, and storing a sensor device in compact. <P>SOLUTION: This bearing 1 with the sensor is applied to a double row angular ball bearing, and a central position C between rolling faces 5, 6 of both rows is axially deflected to a central position of an axial width of inner and outer rings 2, 3. A sensor mounting space S capable of incorporating components of the sensor device 11 is formed at an end side with respect to the rolling faces 5, 6 between the inner and outer rings 2, 3 at an anti-deflection side, and the sensor device 11 is incorporated in the sensor mounting space S to detect relative rotation of the inner and outer rings 2, 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
