The invention relates to a top fairing adjusting device of a commercial vehicle. The adjusting device comprises an operating rod (1), a universal joint (2), a stabilizing support (3), a first fixing support (4), a second fixing support (5), a thrust rod (6), a third fixing support (7) and a connecting rod (8). The two third fixing supports (7) are fixedly connected to the flow guide cover body (9) respectively, one end of the thrust rod (6) is in sliding screwing fit with one third fixing support (7) through threads, the other end of the thrust rod (6) is hinged to a connecting shaft of the universal joint (2) through a middle connecting rod, and the middle of the thrust rod (6) is rotationally connected with the second fixing support (5). The two ends of the connecting rod (8) are fixedly connected with the two third fixing supports (7) respectively, and one end of the operating rod (1) is hinged to the other connecting shaft of the universal joint (2). The air resistance during high-speed running of the vehicle is reduced, fuel consumption is reduced, and the fairing is adjusted and is convenient to use.
