The present invention provides a mounting structure of a flap door for a bus, rotating to allow the flap door to be moved upward and downward to open and close a cargo box formed on one side surface of the bus to be opened and closed. The mounting structure of a flap door comprises: the flap door; a joint bracket; and a lifter. The flap door is rotationally coupled to one end of a joint guide having the other end rotationally coupled to a chassis. The joint bracket is spaced from the joint guide and is fixedly coupled to the flap door. The lifter has one end rotationally coupled to the chassis and the other end rotationally coupled to the joint bracket to pressurize the joint bracket to be rotated. The joint bracket has a slit formed by perforating the joint bracket. A coupling part of the lifter is coupled to the slit to be slid, thereby increasing the extendable length of the lifter or an amount of a rotation of the joint bracket when the flap door is opened and closed. According to the present invention, the flap door can be closed in such a manner that the flap door comes in close contact with the chassis without adjustment of the pressure of gas filled into the lifter, and a deflection caused when the flap door is opened can be compensated.

    본 발명은, 플랩도어가 상승하강하도록 회동하여 버스의 측면에서 개구되도록 형성된 화물함을 개폐하는 버스용 플랩도어의 마운팅구조에 있어서, 일단이 차체에 회동가능하게 결합된 조인트가이드의 타단에 회동가능하게 결합된 플랩도어;와 상기 조인트가이드와 이격되어 플랩도어에 고정결합된 조인트브라켓; 및 상기 조인트브라켓을 가압하여 회동시키도록 일단은 차체에 회동가능하게 결합되고 타단은 조인트브라켓에 회동가능하게 결합된 리프터;를 포함하고, 상기 조인트브라켓은 슬릿이 타공되며 상기 슬릿에는 리프터의 체결부가 활주가능하게 결합되어 플랩도어의 개폐 시 리프터의 인장가능 길이 또는 조인트브라켓의 회전량이 증대되는 것을 특징으로 한다. 상기와 같은 구성의 본 발명은 리프터 내부에 충진된 가스의 압력을 조절하지 않고도 플랩도어를 차체에 밀착시켜 닫을 수 있으며, 플랩도어의 열림시 처짐을 보상할 수 있는 효과가 있다.
