PROBLEM TO BE SOLVED: To provide a method for achieving opening and closing of a door and the loading or unloading from a driver's seat or a passenger seat of a vehicle in a narrow section easily and safely without losing opening-and-closing operability by facilitating the fabrication at low cost while using electronic/electric parts or the like, which are likely to become a factor of a breakdown, as little as possible.SOLUTION: A front end of a suspension-base of a vehicle door is fixed by a large Z-shaped hinge fitting which moves like a folding screen, and a hydraulic damper or the like is attached to a lower part of a side of a vehicle body and to a lower part of an interior side of the door, so that it can become parallel with the Z-shaped hinge fitting body when the door is opened. The front-door opening/closing device has a frame which constitutes a movement as a parallelogram, wherein the door, the side of the vehicle body, the Z-shaped hinge fitting body, and the hydraulic damper or the like are the upper bottom, the lower bottom, the right hypotenuse, and the left hypotenuse respectively, and all of the apexes of the parallelogram are connected by rotation pins. Depending on how to use a rotating shaft of each of the apexes of the parallelogram in opening/closing the door, the door can be opened while maintaining a parallel state with respect to the side of the vehicle, opened like a common swing door, or opened by combining both of them. |
