A constant velocity joint for connecting two revolving shafts with each other and transmitting rotary motion from one to the other comprising an inner joint member and an outer joint member associated with the two shafts respectively, a plurality of ball elements interposed between the inner and outer members for transmitting torque from one to the other, and a cage member arranged between the inner and outer members for holding the ball elements in position, wherein one or both of the inner and outer joint members, e.g. the inner member, is provided in the peripheral surface thereof with a plurality of ball receiving grooves, each of which extends in the direction of axis of the inner member and gradually deepens in its longitudinal direction toward one end of the inner member, each of opposing side walls of the ball groove being formed therein a recessed portion ranging from substantially the center of the joint to one end of the inner member toward which the ball groove deepen so that the depth of the ball groove that is to be subjected to grinding operation is substantially constant along the longitudinal direction thereof, thereby reducing the area to be ground and thus production cost for the constant velocity joint.
