Claims

[Scope of utility model registration request]

In a ball bearing cage, which is formed by opening on the circumference of one end surface in the axial direction of an annular body made of synthetic resin and having pockets whose inner surfaces are spherical arranged evenly on the circumference, The edges of the opening of the pocket are formed on the same plane, and in the plane part, outside the annular body, and on the inner wall part, in the circumferential direction, there is a curved side wall D and a radius having a predetermined thickness along the spherical shape of the pocket part. In the direction, a recess A with a predetermined width E left along the radius of the annular body,
B, and a groove C having a predetermined width and the same length as the diameter of the spherical surface of the pocket is formed in the circumferential center of the opening edge of the pocket from the center of the pocket toward the opening. Characteristic synthetic resin cage for ball bearings.
