Abstract
The present invention relates to a constant velocity joint used in power transmission shafts for automobiles and the like, wherein a slight pocket clearance is defined between each torque transmitting ball and a ball pocket, while relative axial movement of an inner member and a cage is allowed, thereby ensuring smooth rolling of balls. During axial displacement, the outer surface of the inner member makes angular contact with the inner surface of the cage always at a constant position, thereby reducing the internal slide resistance between the members.
