Abstract
A tripod type homokinetic universal joint which has a tripod member formed with three trunnions, an outer member formed with three track grooves to receive the trunnions, and a cylindrical roller mounted on each trunnion. Each track groove has a pair of roller guide surfaces which are flat and parallel to a plane including the axis of the outer member and the center of the track groove. A ring is interposed between each cylindrical roller and each trunnion and is supported so as to be turnable around an axis which is perpendicular to the axis of the trunnion and parallel to the axis of the tripod member.
