To solve the problems that a wheelchair user needs a considerable force to open a conventional swing door because the wheelchair user pushes it open against the closing force of a door closer, and that the wheelchair always comes into contact with the swing door when leaving a room, causing damage to both.SOLUTION: Adding a door-opening force to a swing door using a torsion coil spring cancels out the closing force of a door closer. When a door handle is in a first position, the spring force of the torsion coil spring does not act on the swing door, but when the door handle is rotated to the second position, the spring force acts as a door-opening force, slowly opening the swing door. A slide roller is allowed to run on the end of the torsion coil spring via a slide rail, and in the second position the slide roll rides up onto the wedge material and abuts against the swing door panel surface. The pair of door handles are provided on the left and right sides of the swing door at a predetermined height so that they can be operated by wheelchair users, and the pair of door handles are linked together by a link or chain so as to operate in conjunction.SELECTED DRAWING: Figure 1
