<p>An end plate (20) for the side closing of a box is rotatably coupled to a support part (10) fixed to a structure. A flexible traction element (30) has a first end (31) fixed to an anchoring (21) of the plate (20), a middle part (33) supported on a support surface (23) of the plate (20), and a second end (32) fixed to an anchoring (42) of a sliding block (40) assembled in the support part (10) and coupled to a screw spindle (41) which can be actuated to move the sliding block (40) for the purpose of varying the angular position of said end plate (20) with respect to the support part (10). Fixing means allow fixing the end plate (20) with respect to the support part (10) in a selected angular position.</p> |
