PROBLEM TO BE SOLVED: To provide a bearing quickly discharging lubricating oil to the outside by improving an oil discharge performance without narrowing a gap of a bearing, through which the discharged lubricating oil passes. SOLUTION: This bearing 10 includes: an inner ring 11; an outer ring 12 provided coaxially with the inner ring 11 outside the inner ring 11; and a plurality of balls 13 rolling on and in contact with an outer circumference 11a of the inner ring 11 and an inner circumference 12a of the outer ring 12, wherein lubricating oil is supplied between the inner ring 11 and the outer ring 12 from one side face 10a. The bearing also includes a tapered member 20 provided to the other side face 10b of the bearing 10, having: an outside diameter D1 on one end arranged on the other side face 10b side not larger than the outside diameter D1 of the inner ring 11 on the other side face 10b of the bearing 10; and an outside diameter D2 on the other end larger than the outside diameter D1 of the inner ring 11 on the other side face 10b of the bearing 10, the outside diameter getting larger from one end toward the other end.
