According to the present invention, an operating arm folds a cover of a loading compartment of a truck comprising a rotary shaft disposed on a side wall of the loading compartment and rotated by a drive means, a cover frame of a second cover unit rotatably mounted on an upper portion of a support bar mounted on the rotary shaft, a first cover frame, and the second cover frame. One side of a first operating arm of the operating arm is rotatably mounted on a bracket supporting the rotary shaft. The other side of the first operating arm is hinged and mounted on a second operating arm. A stopping bump is formed on one end of a hinge of the second operating arm. A stopping protrusion protrudes on one side of a hinge of a third operating arm hinged and mounted on the second operating arm to be stopped in response to the stopping bump of the second operating arm. A stopper is disposed on the other side of the third operating arm and rotatably mounted on a hinge shaft. The stopping bump and the stopping protrusion are directly formed on the operating arm to fold the cover. In folding the cover, if the cover is unfolded to at least a prescribed range, the stopping protrusion formed on the third operating arm is stopped on the stopping bump formed on the second operating arm to prevent the cover from being further opened to prevent the second cover unit from being completely opened even if a spring is relaxed or damaged to prevent an accident and a traffic accident.

    본 발명은 적재함 측벽에 구비되며 구동수단에 의해 회전되는 회동축과, 상기 회동축에 결합되는 지지바의 상부에 회전 가능하게 결합된 제2덮개부의 덮개프레임과, 제1덮개부와 제2덮개부로 이루어지는 트럭 적재함 덮개를 절첩하기 위한 작동암에 있어서, 상기 작동암의 제 1작동암의 일측은 회동축을 지지하는 브라켓에 회전 가능하게 결합되고, 상기 제1작동암의 타측은 제 2작동암에 힌지 결합되도록 하되, 상기 제 2작동암의 힌지의 일단에는 걸림턱이 형성되도록 하며, 상기 제2작동암과 힌지 결합되는 제 3작동암의 힌지 일측에는 상기 제 2작동암의 걸림턱에 대응하여 걸릴 수 있도록 하는 걸림돌기가 돌출 형성되고, 상기 제 3작동암의 타측은 힌지축에 회전 가능토록 결합되는 스톱퍼를 구비하는 트럭 적재함 덮개용 작동암를 제공하기 위한 것으로, 본 발명의 효과로는 덮개를 절첩하기 위한 작동암에 직접 걸림턱과 걸림돌기를 형성하되 이들이 절첩됨에 있어 일정 범위 이상 펼쳐지면 제3작동암에 형성된 걸림돌기가 제 2작동암에 형성된 걸림턱에 걸리도록 하여 더이상 펴지지 않게 되어 제 2덮개부가 설령 스프링이 이완되거나 파손되었다고 하더라도 완전히 젖혀지는 것을 방지함으로써 안전사고 및 교통사고를 유발하는 사태를 방지할 수 있는 매우 유용한 발명인 것이다.
