The assembly comprises a fixed fork (10) of which the lugs (22, 30) support a rod (60) onto which a spherical ball is slipped (46) about which a cage (44) and a support (42), of the part which is mobile in rotation, swivel. The maintaining of the axial and angular positions of the spherical ball (46) in the fork is ensured, in particular, by a tight fit (A3) which replaces conventional screw and nut systems positioned at the end of the rod and which project disadvantageously. According to the invention, a pair of planar facets which are opposing and in abutment (including 23) carry out a blocking of one of the assembly pieces in rotation. Application to bell cranks for the transmission of movement, in particular in aircraft engines.
