Abstract: A ball joint has a housing forming a cavity, a ball in the housing, and a stem fixed to the ball and extending downward out of the housing. A rigid cover fixed in the housing upwardly closes the cavity over the ball and a metallic lower ball cup in the cavity traversed by the stem is engaged between a lower portion of the ball and the housing and is complementarily fitted to the lower portion of the ball. A metallic plate-like upper ball cup between the ball and the cover is separate from and out of contact with the lower ball cup and has cutouts defining at least one portion bearing resiliently upward on the cover and at least one portion bearing resiliently downward on the ball.
