ABSTRACT:
A ball joint or ball-and-socket joint assembly includes a ball unit terminating in a ball at one end and a socket unit terminating in a socket at one end, whereby the ball of the ball unit is movably received in the socket of the socket unit, so that the ball unit may move relative to the socket unit over a predetermined angle in all planes passing through a common center line defined by the socket. The ball unit includes a ball section, a cut-away section, a nut section and a threaded section in the order mentioned from top to bottom, and the ball section includes an extended portion which is formed by plastic deformation when the ball section is subjected to roll rolling and which partly extends into the space defined by the cut-away section to thereby provide an increased spherical contact surface which may be brought into sliding contact with a spherical surface of the socket.
