A folding door apparatus having a folding door (11) made up of a pair of door bodies (12) with the internal ends of the paired door bodies (12) rotatably connected together so that the door bodies (12) can be folded at the internal ends; guide hinge bodies (21, 61) fitted to the upper and lower portions of each of the door bodies (12) of the folding door (11); and guide rails (81, 91) for supporting and guiding, through the guide hinge bodies (21, 61), the door bodies (12) of the folding door (11) as they are folded together for opening the door (11) or stretched flat for closing the door (11). The guide hinge bodies (21, 61) each have a base (22), a hinge mechanism (23) and a support member (24, 62). The support member (24, 62) is mounted rotatably on the base (22) through the hinge mechanism (23). The base (22) is secured to the outer end of each door body (11). The support member (24, 62) is provided with a guide member (25, 63) supported movably by the guide rail (81, 91) and is formed with a connector portion (42, 69) which removably connects together the support members (24, 62) on the paired door bodies (12) that come close to each other when the door bodies (12) are folded to the extreme open condition.
