摘要： The present invention relates to a bearing apparatus with a sensor and a rolling bearing with a sensor used to movers such as automobiles or railway carriers, facility machines of equipment, or machine tools. One of the embodiments comprises a sensor (120) for detecting conditions of a supported rotating shaft or of the rolling bearing (111), a ring shaped sensor cover (126) secured to one end face in an axial direction of a stationary-side bearing ring (13), and a ring shaped sensor holding member (121) secured to the sensor cover (126). A plurality of positioning pins (127) of the sensor holding member (121) are fitted in corresponding fitting holes (126d) of the sensor cover (126), so that the sensor cover (126) and the sensor holding member (121) are positioned. In another embodiment, the sensor cover is attached to the bearing ring by caulking in a concave groove at a plurality of caulking positions. A magnet holder of magnetic material placed on the inner ring extends towards the outer ring and functions as a cover shielding the bearing space.
