SOLUTION: In the retainer 6 of a turning bearing arranged a required number of pockets accommodating rollers by partitioning a pair of gentle arc-shaped side walls 7 and 7 by means of pillars 8 arranged in designated intervals, the pillars 8 are alternately slanted each other in a directly-opposed state at a circumferential direction, and the retainer 5 is supported b keeping in contact with the rollers 3 and 4 and pillar 8, and a space existing between the under surface of the retainer 6 and raceway surfaces 1a and 2b is formed therein. Thus, the lubricating agent is supplied and circulated into the pockets 9 and 9a through the space, and lubricating performance of rolling contact surfaces among the roller 3 and 4, the pockets 9 and 9a, and the raceway surfaces 1a and 2b and sliding surfaces among the retainer 6 and raceway surfaces is improved accordingly. Consequently, surface damage is controlled, and fatigue life is further satisfactory.
