A retainer plate7ais fitted on a smaller-diameter step portion9aof an outer ring5a, and a retaining ring11fitted on the smaller-diameter step portion9ais engaged with retaining projections15formed on an inner circumferential surface of a fitting hole12formed through the retainer plate7a, thereby preventing the retainer plate7afrom falling-off from the smaller-diameter step portion9a. 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.
