さを考慮して自然分割を採用している。In the embodiment shown in FIG. 1, the present invention is applied to a cage of a split type thrust cylindrical roller bearing. In this cage 1, two cage divided bodies 2, 3 divided in a semicircular shape along a dividing line L are joined to each other at split openings 2a, 3a, and via a connecting plate 5 connected to the joining portion. Both are connected and integrated in a ring. Integrated cage 1
Has a plurality of pockets 1a for accommodating rollers (not shown).
Are formed at equal circumferential intervals. The dividing means includes natural division (breaking by shearing force) and mechanical division (cutting, etc.)
Although the present invention is not limited to any of them, in this embodiment, natural division is adopted in consideration of good yield and good compatibility between the slit 2a and the slit 3a.

板５の外側面は保持器１の一端面と面一になる。 As shown in FIG. 2 in an enlarged manner (cross section taken along the line c--c in FIG. 1a), one end of the joining portion of the holder divided bodies 2, 3 is provided.
On the surface , from the side of the slits 2a, 3a, respectively, the steps 2b, 3
b, and grooves 2 are formed on the side walls of the step portions 2b and 3b.
c and 3c are provided. The connecting plate 5 has a U-shaped cross section, and is provided with convex portions 5a and 5b on both sides in the circumferential direction. Then, the connecting plate 5 is attached to the recess formed by the steps 2b and 3b from the side of the protrusions 5a and 5b, and the steps 5a and 5b are fitted into the grooves 2c and 3c. Screws 6 are connected to the bottom walls of 2b and 3b. In the state after connection,
The outer surface of the plate 5 is flush with one end of the cage 1.

場合でも、強度としては十分である。The inner dimension S1 between the projections 5a, 5b is determined by the concave grooves 2c, 3c when the slits 2a, 3a are in close contact.
Is approximately equal to the dimension S2 between the wall surfaces, and the convex portions 5a and 5b
By fitting into c and 3c, the circumferential positioning between the cage split bodies 2 and 3 is performed. Further, the force for separating the retainer divided bodies 2 and 3 in the circumferential direction is applied by the engaging force between the convex portions 5a and 5b and the concave grooves 2c and 3c. Is reduced, and strength enough to withstand long-term use is ensured. In addition, in the case where a force for separating the retainer divided bodies 2 and 3 in the radial direction is generated due to the rotation of the retainer 1 or the like, in addition to the above-described configuration, the connecting plate 5 may be disposed on both radial sides. A similar uneven structure may be provided. However, as in this embodiment,
Since the slits 2a and 3a are naturally divided, a shift in the radial direction is suppressed by the matching between the slits 2a and 3a. Therefore, under normal use conditions, there is little need to add an uneven structure. Of course, even if the slit is a machine split, the strength is sufficient.

However, the present invention is not limited to this, and is widely applied to a cage for a split-type rolling bearing in general. It is possible. In addition, the uneven structure,
What is necessary is just to be able to restrain the cage divided body in the separating direction, and its shape and dimensions are not particularly limited.
