An air deflector (50) at a front corner (24) of a cab (20) of a freight vehicle (10), comprising a swirl generator (50) which converts an air flow induced by the vehicle's forward movement to a swirling flow (v) which follows a side (26) of the vehicle (10) situated adjacent to the corner (24) and prevents dirtying of the side (26) from below. The swirl generator (50) comprises a duct (52) which is open downwards, is connected to the cab comer (24), extends curvingly round the corner (24) from the cab front to the cab side (26) and comprises partly an upper end surface (56) and partly opposite sides (58, 60) which are directed downwards, at least one of these sides having a free lower end edge (54). |
