PROBLEM TO BE SOLVED: To ensure watertightness and airtightness of outdoor and indoor sides, and to facilitate opening/closing operations. SOLUTION: In this barrier-free structure of a folding door, one-side parts of two door bodies 8 inside a door frame 1 are turnably coupled together; the other end of one door body 8 is turnably coupled to a door end stile 7 which is provided movably along a guide rail 29 of a head 1b of the door frame 1 and a guide rail 29 of a sill 1b thereof; the door body 8 is folded when the door is opened; and the sill 1b of the door frame 1 is made almost flush with outdoor and indoor surfaces. The guide rail 29 of the sill 1b is formed of a plurality of parallel protrusive streaks; a sliding fitting 30 slidable along the guide rail 29 is attached to the door end stile 7; and a tight material 53B, which is brought into contact with the protrusive streaks 24 when the door is closed, is mounted on the lower part of the door body 8.
