There is provided a structure capable of sufficiently securing sealing performance by a cap (19a). In a state where a fitting insert (44) formed of a nonmagnetic material having a bottomed cylindrical shape is fixed to an inner diameter side of a cap cylindrical part (22a) constituting a cap body (20a) formed of a synthetic resin having a bottomed cylindrical shape, an axially outboard end opening of a through-hole (25a) formed in a cap bottom part (23a) of the cap body (20a) is closed by an axially inboard surface of an insert bottom part (48) of the fitting insert (44). An outer circumferential surface of an insert cylindrical part (47) of the fitting insert (44) is directly fitted into and fixed to an inner circumferential surface of an axially inboard end of an outer ring (2).
