摘要：
A cage (5) for a ball bearing assembly has a pocket (11) for accommodating one of balls defined at a plurality of locations in a direction circumferentially thereof and each of the pockets has an inner surface so shaped as to represent a concaved spherical surface. A concaved portion (13) extending from an open edge on the cage inner diametric side towards the cage outer diametric side is provided in an inner surface of each of the pockets (11). The sectional shape of the inner surface of this concaved portion (13) in a cage circumferential direction is represented by an arcuate shape of a radius of curvature (Rb) smaller than the radius of curvature (Ra) of the concaved spherical surface defining the inner surface of the respective pocket (11). The inner surface of each of the pockets (11) may be formed with a film.
