BUSHING ASSEMBLY

A bushing assembly (1) comprises a bushing element (2) having a first surface (2a), which is adapted to come into contact with a shoulder (S), and a threaded hole (3), which defines and axis (A) and is adapted to be engaged by a screw (20); and a cage element (4), which is fitted around the bushing element (2) so that the bushing element (2) is supported and is floating; the cage element is adapted to be fixed to the shoulder (S) and is provided with at least one opening (5); the opening (5) defines an end abutment (5a) of the cage element (4); the bushing element (2) comprises at least one stop portion (6), which engages the opening (5) with an angular clearance and is movable around the axis (A) at least between a first angular position (I), in which the stop portion (6) is spaced apart from the abutment (5a), and a second angular position (II), in which the stop portion (6) is in contact with the abutment (5a) so as to prevent the bushing element (2) from rotating past the second angular position (II); the stop portion is defined by an appendage element (6), which is distinct from the surface (2a) .
