PROBLEM TO BE SOLVED: To obtain a structure which can entirely simultaneously perform work for inserting rollers into pockets 2a, 2a, and can make the accuracy of shapes of the pockets 2a, 2a favorable even if lengths of the pockets 2a, 2a are shortened in order to hold a short-length roller, related to the structure which can retain the rollers held in the plurality of pockets 2a, 2a.SOLUTION: The pockets 2a, 2a are formed in a plurality of points in a circumferential direction of a main body 1a which is annularly formed of a metal plate having elasticity. Retention pieces 6a, 6a which are bent to a single side in an axial direction are arranged at circumferential single-side edges of the pockets 2a, 2a, and retention pieces 6b, 6b which are bent to the other side in the axial direction are arranged at circumferential other-side edges of the pockets.SELECTED DRAWING: Figure 2 |
