PROBLEM TO BE SOLVED: To improve machinability without reducing the number of outer rings put into a stirring container for surface polishing work in a thrust bearing in which a cage for holding rollers and an outer ring are non-separable with claws provided at the tip of a collar of the outer ring. SOLUTION: High parts 28, 35 relatively higher in axial height H2 than a tip part T of the claw 9 is provided in both side intermediate regions 18, 25 located between the claw 9 and the other claws 10, 16 arranged circumferentially adjacent to the claw 9 in regard to a circumferential direction out of the tips T of the claws 9-16 of the outer ring 4, thereby obtaining such an axial height relationship that the tips T, T of the claws 9, 9 cannot be engaged with each other by the relative height difference H2-H1 of the high parts 28, 35 on both side regardless of an inclination angleθdefined by both outer rings 4, 4 in the overlap state where two outer rings 4, 4 contact at the mutual high parts 28, 35 on both sides, the mutual claws 9, 9 face each other with respect to a direction around the center axis of the outer rings and the tips T, T of the claws 9, 9 are brought closest with respect to a direction along the facing direction.
