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.

摘要： Provided is a fixed type constant velocity universal joint of an eight-ball undercut-free type, which is capable of achieving an improvement of torque capacity at a high operating angle while ensuring durability at the time of a low operating angle. In the fixed type constant velocity universal joint of the eight-ball undercut-free type, a center of a track groove (32) of an outer joint member and a center of a track groove (35) of an inner joint member are separated from a joint center plane (P) respectively to both sides in an axial direction, and are offset to be positioned away from a joint center axis (X) to a radially opposite side relative to the track grooves (35). When Rt represents a distance between a center of a ball (37) and the center of the track groove (32) of the outer joint member, and F represents an axial distance between the joint center plane (P) and the center of the track groove (32) of the outer joint member, a ratio R1 between F and Rt is set to satisfy 0.061≦R1≦0.087, and, when fr represents a radial offset amount as a distance between the joint center axis (X) and the center of the track groove (32) of the outer joint member, a ratio R3 between fr and Rt is set to satisfy 0.07≦R3≦0.19.
