摘要： A constant velocity universal joint is disclosed in which the end of a track groove 24 which opens to the open end surface 26 of the outer joint member 2 is formed with a cut portion 28a, 28b for the incorporation of a ball, thereby making the incorporation of balls possible without shifting the position of the open end surface 26. Therefore, the strength of the inlet portion of the outer joint member 2 is increased. Furthermore, since the ball incorporating angle .alpha. of the cage 5 can be decreased, it is possible to increase the width of the pocket column portion 58 of the cage 5 and increase the strength of the cage 5.
