The present invention provides a safe opening/closing device for a tailgate of a dump truck deck which prevents an accident caused by a fall of an object remaining in a deck onto a road while a tailgate is not fixed. The opening/closing device for a tailgate of a dump truck deck opens and closes a tailgate formed behind a deck installed on an upper portion of a dump truck when the deck is tilted and comprises: a fixing bracket installed on a lower portion of the tailgate and provided with a cylindrical stopping pin; a cylinder mounted on a lower portion of the deck and provided with a piston rod moving forward and backward by pressure; and a stopping ring rotating around a rotary shaft installed on a lower portion of the deck in an L-shape, wherein one end thereof is coupled to an end of the piston rod, and a hook part is formed on the rear end thereof to be stopped on or released from the stopping pin.

    본 발명은 덤프트럭의 상부에 설치되는 데크의 틸팅과 동시에 데크의 후방에 형성되는 테일게이트가 개폐되는 덤프트럭 데크의 테일게이트 개폐장치에 있어서, 상기 테일게이트의 하부에 설치되며 원통형의 걸림핀이 구비되어 있는 고정브라켓; 상기 데크의 하부에 장착되며 압력에 의해 전후로 이동하는 피스톤로드가 구비되는 실린더; 상기 피스톤로드의 단부와 일단이 결합되되, ㄱ자 형상으로서 데크의 하부에 설치되는 회전축을 중심으로 회동하며 후단에는 상기 걸림핀과 걸리거나 해제되도록 후크부가 형성되어 있는 걸림고리;를 포함하는 것을 특징으로 하는 덤프트럭 데크의 테일게이트 안전 개폐장치를 개시한다.
