    Abstract: A cage for rolling bodies of a rolling bearing, which has a first side ring, a second side ring axially spaced from the first side ring, and at least two webs, which connect the first side ring to the second side ring and among each other form a pocket for one of the rolling bodies. At least one of the webs has a first web part disposed at the first side ring and a second web part disposed at the second side ring, and a center web part offset with respect to the first and second web parts. The cage is configured such that it can withstand mechanical stresses via a support element which is provided and which supports the first web part and the second web part and connects the two side rings.

    Abstract: Even when used at a high rotation speed, outside parts in relation to the radial direction of a cage 3, of the circumferential parts of a pocket 7 are kept from being worn away by outside end surfaces 21 of rollers 2. Moreover the rollers 2 are kept from sliding on the inside the pockets 7, to thereby stabilize the performance of rotation support parts.The outside end surface 21 of the roller 2 is made a ball convex surface, so that the center part of the outside end surface 21 can be freely in contact with the inner peripheral surface of a second outside cylindrical portion 14. In a condition with the rollers 2 displaced radially outward of the cage 3 due to centrifugal force, a PV value of a rubbing part between the outside end surface 21 and the opposite surface is kept low, and the wear of this rubbing part is suppressed.

    Abstract: The present invention provides a roller bearing cage and a roller bearing, in which predetermined strength can be obtained without decreasing the number of rollers being able to be arranged while a yield of a material dividing scheme is improved. A thrust roller bearing cage 10 is a plate-shape circular ring in which four arcuate pieces 1a, 1b, . . . are laser welded on laser welding lines 4ab, 4bc, . . . respectively. In the thrust roller bearing cage 10, plural rectangular pockets 2a, 2b, . . . are formed at regular intervals, even at the intervals including the laser welding lines 4ab, 4bc, . . . . Each of the laser welding lines 4ab, 4bc, . . . lies across a total length from an inner periphery to an outer periphery of the circular ring, so that the laser welding line can have sufficient length and bonding strength.
