ABSTRACT:
A fixed constant velocity universal joint with eight balls achieves improvement in cage strength by increasing a smallest outer diameter of a cage and improvement in joint strength at a high operating angle by ensuring required inner spherical area and spherical surface angle in an outer member regardless of the smallest outer diameter of the cage. In the fixed constant velocity joint of the present invention, among eight frontal sections adjacent to an inner spherical surface on an outer member opening side, present between adjacent ball grooves formed on the inner spherical surface, and forming a smallest inner diameter of an outer member opening, any one or any two mutually opposing frontal sections are retracted from the smallest inner diameter in an outward radius direction by a distance required to allow insertion of the cage through the one or two frontal sections (cylindrical surfaces or planar surfaces) in a state in which a cage axial line is perpendicular to an outer member axial line.
