Abstract
A joint of the type in which an outer member and an inner member are each mounted through a ball cage having plural balls mounted in its respective ball windows. The respective balls are in engagement with respective pairs of longitudinally extending ball grooves made in mutually facing surfaces of the respective inner and outer two members, the ball cage is formed at its outer spherical surface with respective longitudinally extending cut-out grooves continuing to the respective ball windows. The respective cut-out grooves are so formed as to have respective contours substantially conforming to respective partition walls between the respective adjacent ball grooves that are formed at the periphery of the mouth of the outer member, so that each partition wall is insertable in each groove.
