Abstract

PURPOSE: To eliminate the need for the space for fitting a magnetic drum and to reduce a magnetic sensor in size on the whole by using one member as both a magnetic drum constituting the magnetic sensor and the inner liner of a bearing in common.
CONSTITUTION: A magnetic material film 9 is provided to one outer peripheral surface 8 of the inner liner 4 of the bearing and the surface is magnetized at specific pitch. A sensor element 12 is fitted to part 11 of the inner peripheral surface of the outer liner facing the film surface 9. This sensor element 12 is a magnetoelectric transducing element which detects the variation of a magnetic field by using Hall effect and detects a magnetic field from the opposite film surface 9. When the bearing having this structure is used as the bearing for a rotating shaft, the space for fitting the magnetic sensor needs not be provided nearby the rotating shaft, so the device is reduced in size on the whole.
