The present invention relates to an opening-closing structure of a side gate for a truck which is installed to pivot on an edge of a truck deck to be opened and closed. The opening-closing structure of a side gate for a truck comprises: a hinge which has a lower portion, fixated to the deck, and an upper portion, fixated to the side gate and is arranged to have a first pipe, formed on the lower portion, and an adjacent second pipe, formed on the upper portion; a spline shaft which is installed in a lengthwise direction of a vehicle body to penetrate the first pipe and the second pipe and has a screw thread formed in a lengthwise direction on the outer circumferential side; and a gear box which is arranged to be gear-engaged with an end portion of the spline shaft, has a lever installed to be able to pivot, and transmits rotation force of the lever to the spline shaft. A screw thread, engaged with the spline shaft, is formed on the inner circumferential side of the second pipe. The first pipes inner diameter is larger than the outer diameter of the spline shaft to allow the spline shaft to rotate. According to the present invention, as the side gate can be opened and closed regardless of workers height, accidents can be prevented, and marketability of the vehicle can be increased.

    본 발명은, 트럭 데크의 가장자리에서 회동하여 개폐되도록 장착되는 트럭용 사이드게이트의 개폐구조에 있어서, 데크에 고정되는 로워부와 사이드게이트에 고정되는 어퍼부를 구비하며, 상기 로워부에 형성된 제1관과 어퍼부에 형성된 제2관이 이웃하게 배치된 경첩;과 제1관과 제2관을 관통하도록 차체길이 방향을 따라 장착되되, 외주면에 나사산이 길이방향을 따라 형성된 스플라인샤프트; 및 스플라인샤프트의 끝단에서 기어치합하도록 배치되고 레버가 회동가능하게 장착되어 상기 레버의 회전력을 스플라인샤프트로 전달하는 기어박스;를 포함하고, 상기 제2관의 내주면에는 스플라인샤프트와 치합하는 나사산이 형성되고, 상기 제1관은 스플라인샤프트의 회전이 허용되도록 상기 스플라인샤프트의 외경 보다 더 큰 내경을 갖는다. 상기와 같은 구성을 갖는 본 발명은 작업자의 키와 상관없이 사이드게이트를 개폐할 수 있으므로, 안전사고 발생을 방지할 수 있으며 차량의 상품성을 더 증대시킬 수 있다.
