Therefore, while the bearing is rotating, the split ends of the cage constantly move in the circumferential direction, and due to the fitting clearance between the uneven parts of the split ends, they also move slightly in the axial and radial directions at the same time. Happens all the time. As a result, abnormal wear tends to occur in the engaging portion of the split end, resulting in poor rotation of the bearing.

圧着するようにされている。 Examples will be described below based on the drawings. In FIGS. 1 to 3, numerals 2 and 3 are divided cage members constituting the cage 1, and 4 is a pocket for holding cylindrical rollers. The divided end surface 6 of the divided end portion 5 of one retainer member 2 has both side surfaces 7a and 7b approximately in the center in the axial direction and on the outer diameter side such that the innermost part in the circumferential direction is narrower than the inlet part. A tapered first engagement groove 7 is formed. and the first
The upper surface 8a is located on the radially inward side of the engagement groove 7 and approximately in the radial center of the split end 6.
A dovetail-shaped second engagement groove 8 connected to the engagement groove 7 of
It is formed continuously in the axial direction from one side surface 5a of the split end portion 5 to the other side surface 5b. The dovetail groove of this second engagement groove 8 is trapezoidal in cross section in the direction perpendicular to the axis. In addition, on the divided end surface 10 of the divided end portion 9 of the other retainer member 3, at a substantially central portion in the axial direction and on the outer diameter side, that is, at a portion that engageably faces the first engagement groove 7. A first engagement protrusion 11 is formed in which both side surfaces 11a and 11b are tapered so that the axial width becomes narrower from the base to the end. The first engagement groove 7 and the first engagement protrusion 1
1, when engaged, each side 7a and 11a, 7b and 11
b are adapted to engage with each other with an appropriate amount of interference. and the first engaging protrusion 11
is located approximately in the radial center of the split end portion 9 on the radially inner side thereof, and the upper surface 12a engages with the portion connected to the first engagement protrusion 11, that is, the second engagement groove 8. A second engaging protrusion 1 is provided on a portion that can be opposed to the second engaging protrusion 1.
2 is formed continuously in the axial direction from one side surface 9a of the split end portion 9 to the other side surface 9b.
The cross-sectional shape of the second engagement protrusion 12 in the axis-perpendicular direction is substantially the same as the trapezoidal shape of the second engagement groove 8 in the axis-perpendicular direction, and the two engage in a dovetail groove. It is like that. Furthermore, the upper and lower surfaces 8a and 8b of the second engagement groove 8 and the upper and lower surfaces 12a and 12b of the second engagement protrusion 12 correspond to the first engagement groove 7 and the engagement protrusion 11, respectively. Due to the tension in the circumferential direction of the first engagement protrusion that occurs when engaged,
It is designed to be crimped.

ため、各面間は圧着係合をすることになる。 Next, the operation of the structure will be explained based on the embodiment shown in FIGS. 1 to 3, but it goes without saying that the other embodiments have similar effects. The divided ends 5 and 9 of the retainer parts 2 and 3 are butted against each other, and the first engagement groove 7 and the first engagement protrusion 11 are connected to the second engagement groove 8.
and the second engaging protrusion 12, respectively. At this time, both side surfaces 7a and 11a and 7b and 11b of the first engagement groove 7 and the first engagement protrusion 11 are engaged with each other with an appropriate amount of interference, so that both divided ends A force acts on 5 and 9 so as to tighten them in the circumferential direction. However, since the second engagement groove 8 and the second engagement protrusion 12 are dovetail-groove engagement, the two divided ends 5 and 9 cannot be separated in the circumferential direction.
Since force is applied between the upper and lower opposed surfaces 8a and 12a, and 8b and 12b of the second engagement groove 8 and the second engagement protrusion 12, the respective surfaces are pressed into engagement.

Due to the engagement with interference between a and 11b, the radial clearance and circumferential clearance are zero.
The vertically opposing surfaces 8a, 8b, 12a, 12b of the second engaging groove 8 and the second engaging protrusion 12 are brought to zero by the press-fit engagement, and as a result, the gap between the two divided ends 5, 9 is reduced to zero. The play in the engaging part is eliminated.
