Abstract: A tripod type constant-velocity universal joint is provided in which a tripod member is prevented from coming out of an outer ring. A guide block is supported on each trunnion of the tripod member mounted in the outer ring. Rolling elements are mounted between raceway grooves formed in both side faces of the guide blocks and raceway grooves formed in both sides of track grooves of the outer ring so that rolling elements will make a pure rolling movement over the entire moving range of the guide block. A lever is mounted to a plate portion of each retainer for retaining the rolling elements. Pins are inserted in a pair of guide grooves formed in the lever. One of the pins is secured to the outer ring and the other pin is secured to the guide block. A stopper ring is mounted to the open end of the outer ring, so that the stopper ring will prevent the rolling elements from coming out of the raceway grooves, thereby preventing the tripod member from coming out of the outer ring.
