A blank is made of a single support which has identical external and internal surfaces to the definitive surfaces (6A,6B) of the internal bush. A cut-out is made in the blank so as to make two primary parts (121,122) the opposite end surfaces (141) of which delimit an insert space. A filling material for the insert space is added so as to realize an added layer (16) enabling this space to be filled in and to form two constituent elements (101,102) of the internal bush. An Independent claim is included for a ball joint. |
