An inner raceway surface (21) and an outer raceway surface (31) include deformed raceway surfaces (2k), (3k) which, in conjunction with the relative rotation of inner and outer rings (2) (3), progressively narrow a clamping gap for a cylindrical roller (4) as allowing the rolling movement of the cylindrical roller (4) thereby imparting a rotational urging force between the inner and outer rings (2), (3) in a direction to eliminate a phase difference caused by the relative rotation.
