PROBLEM TO BE SOLVED: To provide a retainer for an automatic aligning roller bearing increased in the accommodating number of spherical rollers. SOLUTION: The retainer 15 for the automatic aligning roller bearing includes a pair of rings 17, 18, a pair of protuberances 17a, 18a which protrude so as to mutually face from respective ends of the pair of rings 17, 18 and a pillar 19 which connects the pair of rings 17, 18 to each other. In addition, the retainer has a pocket which houses a spherical roller 14 between at least one pair of the protuberances 17a, 18a and the pillar part 19. Then, the thickness dimension L<SB>1</SB>in the circumferential direction of the pillar 19 and the thickness dimension L<SB>2</SB>in the circumferential direction of the protuberances 17a, 18a satisfy L<SB>1</SB>>L<SB>2</SB>.
