An annular member (10) is mounted on an outer ring (4), and a sensor (20) is fixed to the annular member (10). The annular member (10) includes a fixing portion (30), and a cover portion (40). The sensor (20) is fixed to the fixing portion (30) by a bolt (55) and a nut (36). The fixing portion (30) is fixed to the cover portion (40) by bolts (51). The cover portion (40) is separate from the fixing portion (30), and therefore does not have an opening extending in a circumferential direction, and covers a magnet rotor (7) fitted on an inner ring (3) in the circumferential direction.
