摘要： Surface indentation and oil film shortage on rollers is prevented and longer service life of a roller bearing is achieved, by preventing wear debris from being caught and accumulated in pockets of a holder of the roller bearing. Positions and dimensional relations of the diameters of inner and outer ring raceways, the inner and outer diameters of the holder, and inner and outer protrusions which are provided to pillar parts of the holder to prevent the rollers from coming off are defined such that the inner and outer protrusions of the pillar parts always do not come into contact with the outer circumferential surfaces of the rollers in the state where the rollers and the holder are incorporated between inner and outer members. As a result, lubricant oil is smoothly circulated in gaps formed between the outer circumferential surfaces of the rollers and the pillar parts of the holder.
