Abstract: An inventive air guiding device (10) for a trailer (100a), in particular for a utility vehicle (100b), comprises a first air guiding section (11) and a second air guiding section (12) arranged side-by-side in a principal elongation direction (E1) of the air guiding device (10), with a panel (20, 21) defining a contour (13) of the first air guiding section (11). A frame (30) comprises a first frame segment (31) that extends through the first air guiding section (11) and is covered by the panel (20, 21) and a second frame segment (32) that extends through the second air guiding section (12). A first surface portion (15) of the first air guiding section (11) has a greater hardness than a second surface portion (16) of the second air guiding section (12).
