PROBLEM TO BE SOLVED: To prevent the application of overstress to the base end of an outside collar portion 15c of one element 12c as part of a cage 3a even when an outer ring 4, an inner ring 5 and the cage 3a are in eccentric conditions during operation. SOLUTION: The outside collar portion 15c has a circular arc cross section. Two points, the base end (a P-point) and the front end (a Q-point) of the inner peripheral face of the outside collar portion 15c, are put in contact with the whole outer peripheral face of an outside collar portion 15b as part of another element 12b. Thus, when radial load is applied from the inner peripheral face of an outside flange 8 as part of the outer ring 4 to the outer peripheral face of the outside collar portion 15c, the load is distributively borne by two-point contact portions. This construction solves the above issue. COPYRIGHT: (C)2006,JPO&NCIPI
