PROBLEM TO BE SOLVED: To easily fold two door units as folding targets against wind pressure, even when a strong wind pressure is applied in a strong wind during a folding operation. SOLUTION: Regulation rollers 17a-17c are provided on the hinged sides of the door units 10a, 10c and 10e in odd-numbered positions from the hinged side, respectively; and engaging/disengaging rollers 18a-18c are provided in hinge means 12a-12e on the movement end sides of them, respectively. The side of a suspension rail 5 includes: engaging members 20a and 20b which are engageably/disengageably engaged with the engaging/disengaging rollers 18a-18c in the extended state of the door body 7, respectively; ejection members 22a and 22b which eject the engaging/disengaging rollers 18a-18c on the sides of the door units 10a-10f as the folding targets in a folding direction from the engaging members 20a and 20b in the folded state of the door body 7; and a guiding member 25 which guides the engaging/disengaging rollers 18a-18c, ejected by the ejection members 22a and 22b, in the folding direction of separating from the suspension rail 5, in the folded state of the door body 7.
