PROBLEM TO BE SOLVED: To provide a rolling bearing which hardly causes noise and breakage, and is excellent in lubricating performance. SOLUTION: The rolling bearing is a taper roller bearing 11 comprising an inner race 12 having a large flange 12a and a small flange 12b as its flange portions, an outer race (not shown in the figure), a plurality of taper rollers 13 to be arranged between the inner race 12 and the outer race, and a retainer 14 having pockets for retaining a plurality of the taper rollers 13. The retainer 14 is divided into a plurality of retainer segments 14a... by means of dividing lines extending in the axial direction. The retainer segments 14a have a pair of ring portions 15a, 15b, a plurality of beam portions 16 which are arranged within a pair of the ring portions 15a, 15b, and elongate in the axial direction so as to form pockets for retaining the taper rollers 13, and inner race abutting portions 18a, 18b to be brought into contact with the flange portions of the inner race 12 by projecting from the inside diameter surfaces of the ring portions 15a, 15b inward in the radial direction.
