    Abstract: PROBLEM TO BE SOLVED: To provide a small-sized, simple and efficient constant velocity joint.
    SOLUTION: The constant velocity joint assembly 10 is provided with inside and outside joint members (12, 14) having engaging contact surfaces (36, 38) to support the joint for a joint around a common center point A. The joint members have a ball groove 44 branched inside the joint, and the surfaces (46, 48) of their inside and outside ball grooves are offset in the axial direction to the center point in order to push away balls 16 to the inside in the axial direction. A ball retainer 18 is provided inside the outside joint member 12. The ball retainer 18 is energized to be in an engaging state with an end part 52 of the inside joint member 14 by a spring 64, is engaged with the balls 16 in the ball grooves (46, 48), and is pivotally moved around the center point A of the joint in order to hold them while keeping them in a common plane.
