Abstract
A retainer plate 7a is fitted on a smaller-diameter step portion 9a of an outer ring 5a, and a retaining ring 11 fitted on the smaller-diameter step portion 9a is engaged with retaining projections 15 formed on an inner circumferential surface of a fitting hole 12 formed through the retainer plate 7a, thereby preventing the retainer plate 7a from falling-off from the smaller-diameter step portion 9a. The structures and shapes of the various portions are so determined that working or machining can be easily effected to form these portions so as to overcome a problem encountered with the conventional structure.
