<p>PROBLEM TO BE SOLVED: To provide a holder for a roller bearing hardly generating a position deviation while a hold ring can be surely and easily mounted relating to a rib provided in a cylindrical main unit. SOLUTION: This holder 10 for a roller bearing, comprising a cylindrical main unit 11, pocket part 12 incapable of insertion of a roller 40, a pair of disc-shaped ribs 13 protruded to the inward in a radial direction from both end parts of the main unit 11, a pair of cylindrical hold rings 14 respectively connected to an internal peripheral end of each rib 13 to be extended in a direction mutually approaching, and a plurality of pawl parts 15, 16 extended in an axial direction of each hold ring 14 to be capable of slide contact with a rolling surface so as to interpose the roller 40 in a chord direction, has a step difference part 15A for the engaging pawl part 15 capable of engaging with an inner side end face 13A, and the holder is formed to be tapered toward a direction separating from the inner side end face 13A of the rib 13 and an internal peripheral surface of the main unit 11.</p> |
