PROBLEM TO BE SOLVED: To provide a radial roller bearing capable of reducing the number of parts and using a roller with a large diameter. SOLUTION: An inner ring of the radial roller bearing 12 comprising a plurality of cylindrical rollers arranged between an outer ring 14 and the inner ring is formed integrally with a compressor shaft 11. A plurality of spherical bodies 17 are provided so as to roll between the compressor shaft 11 and the outer ring 14, and an axial load acting on the spherical bodies 17 is received by a first load receiving face 18 formed in an inner circumferential face of the outer ring 14 and a second load receiving face 19 formed in an outer circumferential face of the compressor shaft 11.
