In a bar-feed constant velocity universal joint that is offset outward from the center of the plane, the positions of the centers of curvature of the circumferentially adjacent grooves are symmetrical with respect to the trisecting plane of the drive shaft that includes the center of the torque transmission member. A Barfield type constant velocity universal joint characterized by being set so that
