特徴とする円筒ころ軸受用合成樹脂製保持器。 Consisting of a plurality of cage columns and two cage rings integrally formed at both ends of the cage columns, the roller holding pockets formed by the cage columns and the cage rings form a circumference. In a synthetic resin cage for a cylindrical roller bearing that holds rollers at equal intervals, a rib that protrudes in the radial direction is provided on the inner circumferential end surface of the cage column, and a rib is provided at the center of the rib in a direction perpendicular to the axis. A groove with a trapezoidal cross section is provided, and elastically deformable rib walls are formed on both sides of the groove, and a narrow groove with a substantially triangular cross section in the direction perpendicular to the axis is formed in the center of the bottom surface of the trapezoidal groove. A synthetic resin cage for a cylindrical roller bearing, characterized in that the wall thickness of a rib wall that is formed and elastically deforms when the cylindrical rollers are fitted is reduced in two steps toward the inner diameter side.
