ABSTRACT:
A retainer and method of manufacturing the same which makes it possible to form roller stopper lugs reliably on broken surfaces on the side faces of the crossbars formed by punching and also guide surfaces which can guide rollers with high accuracy. A plurality of protrusions are formed on both sides of the crossbars. The surfaces of the protrusions are ironed in both thickness directions to form roller stopper lugs at both ends of the protrusions. The flat surfaces formed on the protrusions by ironing serve as the roller guide surfaces. Thus, the rising and sinking amount of the rollers can be controlled with high accuracy.
