In order to more reliably prevent foreign objects from floating in a bearing space while maintaining the lubrication capability of a roller bearing, in this roller bearing rolling bodies (13) are inserted between an outer bearing ring (11) and an inner bearing ring (12), an aperture at at least one axial end of the bearing space is covered by a seal ring (20), foreign objects included in the lubricating oil are trapped by a filter (23) covering an oil passage hole (22) formed in the seal ring (20), and magnetic bodies (1) that attract the foreign objects by the action of magnetic force are provided adjacent to the inside of the filter (23) in the axial direction. |
