きる。In the second embodiment, FIG.
As shown in (c), since the male screw shaft 10 is inserted from the side of the slits 1a and 2a, the width (P) of the pocket hole 4 and the width (H) of the recess 6 are set in the first embodiment. As in the embodiment, there is no need to have a width enough to allow the bolt 8 to be inserted into the through hole 5 from the pocket hole 4 side through the recess 6.
The width (H) may be such a width that a spanner or the like does not interfere with the rolling elements 3, so that the pocket holes 4 can be further arranged in the vicinity of the slits 1a and 2a as compared with the first embodiment. it can.

A female screw hole is formed, and the other split portion is abutted against the other split portion, and a bolt inserted through the through hole is screwed into the female screw hole. The two split openings are connected by inserting the screwed male screw shaft into the through hole and screwing it with a nut. As described above, since the cage divided body is connected by the bolt or the male screw shaft, and the pocket hole is used for the connection of the slit, the pocket hole can be provided also in the vicinity of the slit. The number of rolling elements and the rated load can be made substantially equal to those of an integrated cage having the same dimensions.

A plurality of cage divided bodies which are divided in a circumferential direction and have a large number of pocket holes for accommodating a large number of rolling elements, are joined to each other at their opposing slits, and are joined together. In the cage for split type rolling bearings constituting the two annular cages, a through-hole is formed which circumferentially communicates one of the opposed slits with a pocket hole in the vicinity thereof, among the opposed slits. A female screw hole is formed in the other slit, and the other slit is abutted against the other slit, and a bolt inserted through the through hole is screwed into the female screw hole. A split type rolling bearing retainer, characterized in that a male screw shaft previously screwed into the female screw hole is inserted into the through hole and screwed together with a nut to connect both split openings.
