PROBLEM TO BE SOLVED: To provide an opening-closing driving device of an accordion door capable of using a common hinge device regardless of an expansion stroke of a body part by generating driving torque in the opening direction or the closing direction of the body part even in any of a folding-in position and an extracting position of the accordion door. SOLUTION: This opening-closing driving device has the hinge device 14 between a moving rail 6 and a fixed rail 7. The hinge device 14 is composed of a hinge part 15 and arms 16a and 16b for connecting the hinge part 15, the moving rail 6 and the fixed rail 7. The hinge part 15 is provided with a cam device for automatically moving the moving rail 6 to a maximum extracting position or a maximum folding-in position in the vicinity of the maximum extracting position and the maximum folding-in position of the body part 3.
