Each arm of a tripod element of a joint has a spherical region. A roller maintained in the plane of two runways therefor provided in a barrel of the joint and having a convex toric inner surface is mounted on the spherical region by means of a ring arrangement of rolling elements having a periphery which has a curvilinear concave shape in axial section of the rolling elements. The mutual contact between the rolling elements prevents the rollers from coming away from the spherical regions. |
