A retainer plateis fitted on a smaller-diameter step portionof an outer ring, and a retaining ringfitted on the smaller-diameter step portionis engaged with retaining projectionsformed on an inner circumferential surface of a fitting holeformed through the retainer plate, thereby preventing the retainer platefrom falling-off from the smaller-diameter step portion. 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.
