ABSTRACT:
The flexible ball joint is provided with a continuous ring mounted inside a casing and supported by an inner spherical surface of one of the segments of the casing and by a cylindrical portion of an end piece element. The respective contacting sides of the ring are concentric with the juxtaposed spherical and cylindrical surfaces, so that the ring is able to be slidably guided by those surfaces in response to an absorbing shock without losing the contact with the surfaces.
