The invention discloses a folding door applied to the slope surface. The folding door comprises a door frame, a door leaf, transmission mechanisms and a track groove arranged in the slope surface. Corresponding angles are set at the bottom of the door leaf according to the height of the slope surface. The door leaf comprises an edge door leaf body and a middle door leaf body, one side of the edge door leaf body is connected with the middle door leaf body through hinges, and the other side of the edge door leaf body is connected with the door frame through a rotating shaft. Each transmission mechanism comprises a guide wheel, a bearing pedestal and a counterweight piece. An unthreaded shaft which vertically moves and rotates relative to each bearing pedestal is arranged in the bearing pedestal. Each guide wheel is arranged in the track groove and is connected with the corresponding unthreaded shaft through a bolt, and the other end of each unthreaded shaft is connected with the corresponding counterweight piece. The counterweight pieces are used for applying upward pull force to the unthreaded shafts to drive the guide wheels to slide by being kept to be attached to the upper end of the track groove all the time. Through the transmission mechanisms, the folding door can move on the slope surface. Moreover, the center of gravity of each door body evenly acts on the upper end of the track groove, and thus the door leaf can be folded smoothly. Besides, noise is not liable to be generated.
