A folding door body 20 makes a door-end-side folding door panel 18 turnably coupled to the panel 15, makes a door-tail-side folding door panel 19 turnably coupled to a support such as the wall body W, and makes both the panels 18 and 19 foldably coupled together by engagement of tooth parts of a gear hinge 30 with at least a pair of the arc-shaped cross-section tooth parts wherein tooth spaces are formed in a longitudinal direction. A folding-door starting means E for pushing both the panels 18 and 19 in a folding direction, wherein mutual stile surface sides are separated from the wall body in synchronization with the initial motion of opening of the panel 15, is annexed between the both the panels 18 and 19.
