摘要 <P>PROBLEM TO BE SOLVED: To suppress the labor when assembling a cage while preventing a fall of a cage, securing accuracy in prevention of a fall of the cage by separately providing a partition, and reducing the cost of the cage. Ž<P>SOLUTION: This cage for a bearing comprises: a cage body 10 comprising sliding parts 2a and 2b, which are formed in a partition 2 between pockets 1 and 1, and fall stoppers 4a and 4b for regulating the slip-out amount of a rolling body 3 housed in the pocket 1, and in which holes 11 facing an inner raceway and an outer raceway are arranged in the circumferential direction; and a pocket frame 20 formed with the sliding parts 2a and 2b and the fall stoppers 4a and 4b equivalent to one pocket in a frame part 21. The cage body 10 is formed from an iron-based metal, and the pocket frame 20 is formed from a copper-based metal. When the cage body 10 and the pocket frame 20 are assembled with each other, while preventing a contact of the fall stoppers 4a and 4b with the rolling bodies 3, by press-fitting the frame part 21 inside the hole 11 in the condition wherein the rolling bodies 3 are housed in the hole 11, the pocket frame 20 is positioned relative to the cage body 10, and the pockets 1 with the rolling bodies 3 can be formed.
