PROBLEM TO BE SOLVED: To provide a current-carrying bearing capable of ensuring allocation of conductivity to a bearing while preventing infiltration of abrasion powder of a current-carrying brush into the bearing.SOLUTION: A conductive bearing comprises a current-carrying member 30 fixed to an inner circumferential surface 11 of an outer ring 10 near a bearing end portion with respect to a seal 7, for making the inner circumferential surface 11 of the outer ring electrically continuous to an outer circumferential surface 21 of an inner ring 20. The current carrying member 30 includes a spring 31 fixed to the inner circumferential surface 11 of the outer ring 10 and exhibiting conductivity; and a current-carrying brush 32 radially urged by the spring 31 to slidably contact the outer circumferential surface 21 of the inner ring 20 and exhibiting conductivity. The spring 31 and the current-carrying brush 32 are guided radially by first and second guide surfaces 41 and 42 provided between the inner circumferential surface 11 of the outer ring 10 and the outer circumferential surface 21 of the inner ring 11. |
