ABSTRACT:
A fixed constant velocity universal joint of a structure, which easily allows incorporation of an inner ring into a cage without impairing a function of the joint, is provided. The fixed constant velocity universal joint has an outer ring having in an inner spherical surface thereof a plurality of track grooves arranged at equal circumferential intervals and extending axially toward an open end, an inner ring having in an outer spherical surface thereof a plurality of axially extending track grooves paired with the track grooves of the outer ring and arranged at equal circumferential intervals, a plurality of balls interposed between the track grooves of the outer ring and the track grooves of the inner ring, for transmitting torque, and a cage interposed between the inner spherical surface of the outer ring and the outer spherical surface of the inner ring, for holding the balls, in which an outer ring open end side of the outer spherical surface of the inner ring is cut off, with a boundary portion between a cutoff portion thereby obtained and the outer spherical surface being rounded.
