Abstract:
A cage of a ball bearing includes an annular portion located on a first axial side with respect to balls, the first axial side being one side in an axial direction of the ball bearing, and cage bars extending from the annular portion toward a second axial side, the second axial side being the other side in the axial direction of the ball bearing. A space located on a second axial side of the annular portion and defined between any two of the cage bars adjacent to each other in a circumferential direction serves as a pocket that accommodates a corresponding one of the balls. The pocket has a contact surface that is brought into point contact with the ball at an intersection point between a rotational center axis of the ball and a surface of the ball when the cage is displaced toward the second axial side.

Claim (Index 3):
The ball bearing according to  claim 1 , wherein\n the pocket has facing surfaces with the contact surface interposed inbetween as a center, one of the facing surfaces disposed on a radially outward side of the contact surface and facing the balls, and the other of the facing surfaces disposed on a radially inward side of the contact surface and facing the balls, and in a neutral state in which a center of the pocket and a center of the ball coincide with each other, a clearance formed between the ball and the facing surface on the radially outward side of the contact surface and a clearance formed between the ball and the facing surface on the radially inward side of the contact surface are larger than the clearance formed between the ball and the contact surface in the neutral state.
