Figure 1 is a sectional view of the main parts of a cylindrical roller bearing using the cage of this invention.The cage is cut in the axial direction at the center of the pocket.1. Outer ring, 2. Inner circle, 3
．． Coro, 4. In the retainer, 43 represents a concave groove.
FIG. 2 is a partial perspective view of the retainer used in FIG. 1 before being assembled, 41 is a pocket, and 42 is a column.
Figure 3 is an enlarged sectional view of the main part of the column 42 in the circumferential direction.
indicates a concave groove. FIG. 4 is a view of a conventional pocket cut in the circumferential direction, showing a state in which the convex burrs generated at the parting line and the rollers are in contact with each other.

動体コロ３を保持するポケツト４１，４１……を
区分している柱４２，４２……を持つた形状に対
し軸方向の型抜きにより成形される保持器におい
て、各柱４２のコロ保持面の中央部に一定の凹溝
４３を持つた円筒コロ軸受用樹脂製保持器。 By punching in the axial direction, the shape has pillars 42, 42, which separate the pockets 41, 41, which hold the rolling element rollers 3, which are equally distributed around the circumference of a cylindrical body made of synthetic resin. A molded cage made of resin for a cylindrical roller bearing has a certain concave groove 43 in the center of the roller holding surface of each column 42.
