Abstract
A tripod type universal joint wherein the ball rollers and the needle rollers on which they turn are retained on the trunnions by holding constructions which comprise each: a circlip engaged in a groove on the end of the trunnion; and an annular retainer, which is formed with an inner cylindrical surface which fits snugly over the trunnion, a cutaway with a tapered entrance which guides the circlip into the hole of the retainer and compresses it by a sliding and squeezing action, a circlip stop face which stops the retainer from coming off the trunnion, when the circlip has expanded so as to oppose the stop face, and ball roller and needle roller stop faces which retain the ball roller and the needle rollers on the trunnion.
