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.

摘要： A constant velocity universal joint has high strength and capable of suppressing deformation caused by quenching at an opening end portion of a track groove of an outer joint member. In an undercut-free constant velocity universal joint in which a track groove in a cup portion of the outer joint member has a hardened layer formed by induction quenching, an opening end surface is protruded by a protruding amount t in an axial direction from a groove bottom of the track groove in a relief surface. The protruding amount t satisfies a relation of t=0.037d to 0.185d when a diameter of a torque transmission ball is represented by d. The opening end surface in a protruded portion and an outer surface of the cup portion continuous to the opening end surface have an unhardened layer free from hardening by quenching.
