PROBLEM TO BE SOLVED: To provide a roller bearing, capable of reducing slide abrasion or slide resistance of an outer ring receiving an axial load, and achieving favorable assemblage performance. SOLUTION: A plurality of needle rollers 4 are incorporated between a roller 3 that functions as the outer ring and a bush 2 that functions as an inner ring, and a thrust bearing plate 7 to be installed on the outer circumference of the bush (inner ring) 2 is disposed to face each side surface of the roller (outer ring) 3 in a chain. A track groove 8 is provided in each side surface of the roller (outer ring) 3 facing the thrust bearing plate 7, and between the track groove 8 and the thrust bearing plate 7, a plurality of balls 9 are held to be capable of rolling.
