<p>The device (1) has a substantially box-shaped supporting element (2) fitted to the vehicle body (3), and in turn having a top opening (4), and a bottom opening (21) closed by a cover (22) fitted along its outer periphery to the edges defining the bottom opening (21) and which is subject to in-service vibration. The supporting element (2) has two lateral walls (19a, 19b) laterally defining the bottom opening (21); a front and a rear wall (18a, 18b) crosswise to the lateral walls (19a, 19b) and transversely defining the bottom opening (21); and an inner wall (27) interposed between the lateral walls (19a, 19b), extending parallel to the lateral walls (19a, 19b), extending crosswise to the front wall (18a) from the center line of the front wall (18a), and defining a further constraint for the cover (22) to reduce the in-service vibration of the cover (22). <IMAGE></p> |
