PROBLEM TO BE SOLVED: To prevent a contact with a wire from below of a self-closing device, the wire being drawn out when a door body of a folding door opens.SOLUTION: A door tail-side edge of a first door body 1 and a door end-side edge of a second door body 2 are connected rotatably, the first door body being suspended rotatably via a shaft 84 from a door roller 8 movable in an opening width direction in an upper frame 3, and the second door body being supported rotatably at the door tail-side. A self-closing device 9 is provided inside the upper frame 3 on a door end-side, the self-closing device 9 being connected with the door roller 8 by a wire 10. When a folding door opens, the wire 10 is located directly above a groove 33 in the upper frame 3 and is drawn out in the opening width direction. A closing member 11 for closing the groove 33 is provided in the upper frame 3 on a door end-side portion, below a height position to which the wire 10 extends.
