Abstract

Each pocket of a cage have a cylindrical surface formed by a cylindrical shape having a center line extending in a radial direction, and a tapered surface contiguous with the cylindrical surface. A radial displacement of the cage is regulated by a contact of the ball with the tapered surface. In a state in which the ball is in contact with the tapered surface, an angle formed by an imaginary line extending through a contact point between the ball and the tapered surface and the center of the ball, and an imaginary perpendicular plane extending through the center of the ball and perpendicular to the radial direction, is larger than a friction angle defined by a friction coefficient at the contact point between the ball and the tapered surface.
