PURPOSE: A back door of a van is provided to offer convenience in the loading and unloading of a load by making a lower back door is opened downwardly. CONSTITUTION: A back door(12) is divided into an upper back door(14) and a lower back door(16). The upper back door is slid vertically by the operation of a pneumatic cylinder(26). The lower back door is rotated by a hinge bracket(30). According to the structure, a space for opening and closing the back door is not needed. Further, since the upper back door is opened by the pneumatic pressure and the lower back door is opened downwardly, a load is loaded and unloaded conveniently.
