본 발명의 화물 차량은 주행풍이 통과되는 스포일러 통풍구(23)를 형성하면서 항력계수를 줄여주는 스포일러 바디(20), 후방 슬라이딩 이동으로 플랩 도어(40)를 잡아당겨 스포일러 통풍구(23)를 개방하는 반면 전방 슬라이딩 이동으로 플랩 도어(40)를 밀어 올려 스포일러 통풍구(23)를 막아주는 플랩 조작기(50)로 구성된 루프 스포일러 장치(10)가 실내 환기를 수행하는 선루프(10-1)와 함께 운전석(3)의 루프(roof)(3-1)에 구비되고, 상기 플랩 도어(40)가 선루프(10-1)의 오픈과 클로즈에 연동되어 스포일러 통풍구(23)를 개방 및 차단함으로써 선루프(10-1)의 실내 환기 성능 저하 없이 항력계수 저감에 의한 연비개선효과를 구현하는 특징을 갖는다.

    According to the present invention, a freight vehicle has a roof spoiler device (10) provided on a roof (3-1) of a driver′s seat (3) together with a sunroof (10-1) for performing indoor ventilation, in which the roof spoiler device (10) includes: a spoiler body (20) for reducing a drag coefficient while forming a spoiler ventilation opening (23) through which a travelling wind passes; and a flap manipulator (50) for pulling a flap door (40) by a rear sliding movement to open the spoiler ventilation opening (23) while pushing up the flap door (40) by a front sliding movement to shut the spoiler ventilation opening (23). In addition, the flap door (40) is interlocked with opening and closing of the sunroof (10-1) to open and shut the spoiler ventilation opening (23), so that fuel efficiency is improved by reducing the drag coefficient without reducing indoor ventilation performance of the sunroof (10-1).
