Patent attributes
A fixed type constant velocity universal joint includes an outer joint member having a cup shape, an inner joint member, which is received in the outer joint member, and transmits torque between the outer and inner joint members through intermediation of balls while allowing angular displacement, and a shaft, which is coupled to the inner joint member so as to allow torque transmission. A recessed portion is formed in a bottom portion of the outer joint member, and an embedded stopper that enters the recessed portion of the outer joint member is mounted to a shaft end portion of the shaft opposed to the recessed portion. The embedded stopper is allowed to interfere with the recessed portion of the outer joint member at an angle that is smaller than an incorporating angle of the balls and larger than a maximum operating angle during use of the joint.
