The ball joint has a cavity (2) formed in a housing (1) that receives the pivot (3) and is open only in its upper part. It is arranged to form the side wall and base for the spherical part (3a) of the pivot. The cavity is closed in its upper part by an inserted ring (13) with an opening (13a) that encloses the pivot. The ring retains the cage (4) that encloses the spherical part of the pivot. The ring has a spherical internal surface that continues the spherical surface of the cage. |
