A drawn cup roller bearing includes: an outer ring including a raceway surface; a first rib formed at one end of the outer ring by being bent substantially perpendicular to the raceway surface; a second rib formed at the other end of the outer ring by being bent inwardly so as to be substantially parallel to the raceway surface; a cage including pockets for holding rollers, respectively; and an annular projection stopper which is projected radially outwardly and provided over an entire outer circumference at a pocket side position of an outer circumferential surface of the cage. An end surface of the cage abuts against a part of the first rib and the annular projection stopper is interposed between an end surface of the second rib and the rollers in a state that the cage is assembled into the outer ring. |
