CAGE FOR ROLLER BEARING, ROLLER BEARING, AND METHOD OF MANUFACTURING ROLLER BEARING

摘要

PROBLEM TO BE SOLVED: To provide a cage for a roller bearing reducing the wear of a housing.

SOLUTION: A column 14 is formed in a V-shaped cross section with its center bent radially inward. The center 15 of the column 14 is formed with an inner diameter side roller slip-off preventing part 17 narrowed in the inner diameter side dimension. Ends 16 of the column 14 are formed with outer diameter side roller slip-off preventing parts 18 molded wide being pressed to the outer diameter side by a press or the like. When the radial thickness dimension of each of annular parts 12a, 12b is set to A, the thickness dimension of the end 16 of the column 14 is set to B and the radial thickness dimension of the center 15 of the column 14 is set to C, a relationship of A>B and C>B is established.
