Summary:PROBLEM TO BE SOLVED: To provide a plastic holder for a roller bearing, durable without being damaged under disadvantageous operated conditions, having both-side side rings 1, 2 spaced from each other in the axial direction and a plurality of cross pieces 3 extending in the axial direction for joining the both-side side rings 1, 2 with each other, the cross pieces 3 which are distributed over the circumference of the side rings 1, 2 to form pockets 4 storing rollers 5 together with the both-side side rings 1, 2, the both-side side rings 1, 2 having different diameters, so that the plastic holder can be manufactured by using a tool mov able to the axial direction during injection molding. SOLUTION: Each of the cross pieces 3 has a first guide surface 6, protruding to the outside in the radial direction, so that the holder can be guided on the flange 18 which is protruded outside from the both-side side rings 1, 2 in the radial direction, provided on the outer ring 17 of the rolling bearing and turned to the inside in the radial direction.
