Claims

[Claims for Utility Model Registration] 1. A cage is disposed between an outer ring and an inner ring, and the cage has two annular portions spaced apart in the axial direction and a plurality of columns spaced apart in the circumferential direction. In the roller bearing, which is integrally connected by the two adjacent pillars and has the rollers arranged in pockets surrounded by the two adjacent pillars and the two annular parts, the retainer is made of synthetic resin, and the outer circumferential surface of the pillar The distance between the outer circumferential surface of the adjacent column is shorter than the diameter of the point where the rollers face each other, and the distance between the inner circumferential surface of a certain column and the inner circumferential surface of the adjacent column is the point where the rollers face each other. What is claimed is: 1. A roller bearing characterized in that a radial groove is provided at the boundary between the side surface of the column forming the pocket and the annular portion, each having a portion shorter than the diameter thereof. 2. The roller bearing according to claim 1, wherein the boundary between the side surface of the material and the annular portion has a radial groove in at least one of a radial outer circumferential portion and an inner circumferential portion. 3. The roller bearing according to claim 1, wherein at least one of the outer peripheral surface of the pillar and the inner peripheral surface of the pillar has an axial groove. 4. The roller bearing according to claim 1, wherein the axial center of the side surface of the pillar has a concave portion. 5. The roller bearing according to claim 1, wherein the roller bearing is a self-aligning roller bearing. 6. The roller bearing according to claim 5, wherein the spherical roller bearing is a double-row spherical roller bearing. 7. The clearance between the inner peripheral surface of the pillar of the annular part on the side surface of the roller bearing is the same as the gap between the inner peripheral surface of the pillar of the annular part on the side surface of the roller bearing and the outer peripheral surface of the pillar. The roller bearing according to claim 6, which is larger than the gap between the roller and the roller.
