摘要：
A ball bearing cage is formed with pockets (7) each having an inwardly curved spherical pocket face similar to a ball in shape. At least one of the pockets (7) has a protrusion (8) projecting inwardly thereof from one of inner and outer circumferential edge portions of the pocket face. A ball bearing comprises balls retained between inner and outer bearing rings and equispaced circumferentially thereof by a cage. The cage is formed with pockets each having an inwardly curved spherical pocket face similar to the ball in shape, at least one of the pockets having a protrusion projecting inwardly thereof from an edge portion of the face close to the fixed one of the rings.
