<P>PROBLEM TO BE SOLVED: To provide a ball bearing for a tripod type constant velocity universal joint equipped with an outer ring, an inner ring, a plurality of balls and a retainer wherein the retainer can be assembled even when a number of the balls arranged between the inner ring and the outer ring is increased and a space between the balls is narrow in order to enhance bearing load capacity with respect to radial load. <P>SOLUTION: The retainer 9 comprises a plurality of spacer members 9a intervening between the balls 6, and at least one of the plurality of the spacer members 9a is constituted by an elastic material. The spacer member 9a constituted by the elastic material is elastically expanded and contracted along the bearing peripheral direction, and is assembled in the narrow space between the balls 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
