Abstract
A guiding ring (4) having a spherical inside surface is supported inside an annular rubber cushion (3) which in turn is supported inside a metal case (1). A body (2) having a spherical outer surface cooperates with the inner surface of the ring to permit rotational movement. Bellows (5) attached to axial abutments (6,7) of the case protect the joint from abrasive elements. The case is preferably in two parts which are press fit together, the rubber cushion being fixed inside one of the parts.
