Abstract:
PROBLEM TO BE SOLVED: To provide a cage for a radial roller bearing which can regulate the relative movement of first and second cage elements in an axial direction.SOLUTION: One-end faces 30a, 30b of first and second cage elements 9a, 9b in a circumferential direction have at least one of one-end side protrusions 31a, 31b, respectively, which are protrusively formed toward one-end sides in the circumferential direction, and other end faces 40a, 40b of the first and second cage elements 9a, 9b in the circumferential direction have at least one of other-end side recesses 41a, 41b, respectively, which are recessively formed toward one-end sides in the circumferential direction. The one-end side protrusion 31a of the first cage element 9a is fit into the other end side recess 41b of the second cage element 9b, the one-end side protrusion 31b of the second cage element 9b is fit into the other end side recess 41a of the first cage element 9a, and thus the relative displacement of the first cage element 9a and the second cage element 9b in an axial direction is regulated.
