PROBLEM TO BE SOLVED: To provide a roller bearing to reduce wear of a pin and be excellent in impact resistance and machinability after hardening treatment. SOLUTION: A roller bearing comprises a plurality of rollers; a pair of annulus ring-form side plates to nip the two ends of the roller therebetween; a pin 4 inserted through a rotary shaft to rotatably hold the shaft and securely intercoupling the two annulus ring-form side plates; and an outer ring and an inner ring 6 relatively rotated around a shaft AX through the rollers. The drum part 41 of the pin 4 forms a slide contact part making contact with the inner surface of a through-hole formed in the roller. Taper-form screw parts 42 screwed in respectively screw holes are formed at equal intervals in the periphery of one annulus side plate 2, and weld parts 43 securely inserted in respective openings formed at equal intervals are formed on the periphery of the other annulus ring-form side plate. |
