Abstract
A fixed type constant velocity joint includes a cylindrical joint outer ring having an inner spherical surface formed with circumferentially equispaced axially extending track grooves, a joint inner ring having an outer spherical surface formed with circumferentially equispaced axially extending track grooves, balls disposed in ball tracks defined by cooperation between the track grooves in the joint outer and inner rings, and a cage for holding the balls in the ball tracks. The rear open end of the joint outer ring has an inner diameter larger than the outer diameter of the joint inner ring, an inner diameter surface of said cage is a surface having a shape such that the region located forwardly of the axial center is capable of controlling the forward movement of the joint inner ring while the region located rearwardly of the axial center is capable of allowing the axial movement of the joint inner ring.
