  2. Description of the Related Art In recent years, a wing vehicle in which an L-shaped wing roof that covers an upper portion and a side surface of a loading platform so as to be openable and closable is provided on both left and right sides of a center frame above the loading platform has been widely used. In addition, a lashing rail for attaching the end of the baggage tightening belt is provided inside the wing roof. In this case, it is desirable that the top surface of the lashing rail and the inner wall surface (lining) of the wing roof are substantially flush so as not to damage the load on the loading platform.

  FIG. 5 shows a conventional wing roof 1 with a lashing rail. The wing roof 1 with a lashing rail is rotatably attached to both sides of a center frame 2 above a loading platform 8 of a wing vehicle via hinges 3, and includes an upper frame portion 4 that covers the loading platform upper surface, and a side surface that covers the loading platform side surface. It has the frame part 5 and the connection part 6 which connects both to L shape. The side frame part 5 has a plurality of square pipe-like longitudinal aggregates 5a, and the lashing rail 10 provided laterally inside the side frame part 5 is fixed to the inside of the longitudinal aggregate 5a. Further, the inner wall surface of the side frame portion 5, that is, the inner wall surface (surface facing the cargo compartment side) 20 a of the lining plate 20 constituting the cargo compartment wall surface is flush with the top surface 10 a of the lashing rail 10. The lining plate 20 is fixed to the inside of the longitudinal aggregate 5a through the spacer 7. An outer plate such as an aluminum plate is fixed to the outside of the upper surface frame portion 4 and the side surface frame portion 5.

  By the way, the thickness of the spacer 7 is 9 mm when the height of the lashing rail 10 is 15 mm and the thickness of the lining plate 20 is 6 mm. When closed, the inner width of the cargo room is narrowed by 18 mm (9 mm × 2). Further, it is necessary to attach a large number (about 30) of spacers 7 to the side frame portion 5 before the lining plate attaching operation, which requires a lot of man-hours.

  In the van type vehicle, an example of a structure in which the top surface of the lashing rail and the inner wall surface of the luggage compartment are flush with each other is shown in Patent Document 1 below.
