Is attached to the rail fixing member 63 with one side edge engaged with the rail fixing member 63 and screwed to the rail fixing member 63 at the other side edge sandwiching the projection 61. Therefore, the rail portion 62 can be easily replaced. Further, a hanging column 7 and a door stop column 8 are provided on the left and right side edges of the door opening 4.

A pair of hanger rollers 9 is provided at the upper end of the hinge member 31 of the folding door 1 that is an even number from the hanging end, and the hanger rollers 9 are opposed to each other inside the hanger rail 5 and are integrally formed. It rolls and runs on the upper surface of the formed guide part 51. Further, the lower end of the hinge member 31 is provided with an engaging member 10 having a downward engaging groove 101 formed by aluminum die casting or the like.
Is engaged with the engaging groove 101. Therefore, the folding door 1
Is hung upward at the position of the hinge member 31 and is movable along the hanger rail 5 and the convex rail 6.

As shown in FIG. 5, the odd-numbered hinge members 32 of the folding door 1 can escape from the hanger rail 5 and the convex rail 6 in the closed state, as shown in FIG. A notch 51 is formed on the escape side of the hanger rail 5 to allow the hinge member 32 to escape. The lower end of the hinge member 32 is formed by aluminum die casting or the like and has an inverted L-shaped cross section, and cannot be engaged with the convex rail 6 in the escape direction of the hinge member 32 but is engaged in the opposite direction. An engagement member 11 having a possible engagement piece 111 is provided. Therefore, in the door opened state shown in FIGS. 5 and 7,
The hinge member 32 escapes from the positions of the hanger rail 5 and the convex rail 6, and the folding door 1 can be folded.

Each door body 2 of the foldable door 1 has an engaging member 12 formed of a mold material such as aluminum fixed to a lower end thereof. The engaging member 12 is hinged to a convex portion 61 of the convex rail 6. An engagement piece 121 that engages in the same direction as the member 32 is formed. A flocking band 122 brushed toward the side surface of the convex portion 61 of the convex rail 6 is attached to the engaging piece portion 121, and is formed by contact between the engaging piece portion 121 and the convex rail 6 when the door is closed. Prevents damage.

At the upper end of the convex portion 61 provided on the rail portion 62 of the convex rail 6, a fitting groove 65 is formed over the entire area in the longitudinal direction, and the seal member 13 made of a flocking band fits into the fitting groove 65. doing. The seal member 13 protrudes upward toward the lower end of the foldable door 1 located on the protrusion 61, and elastically contacts each door body 2 and the hinge member 3 when the door is closed. The projecting amount of the seal member 13 is set to a length projecting about 2 mm from the clearance from the upper end of the convex portion 61 to the lower end of the folding door in the upward direction. Therefore, in the door closed state, the upper end of the seal member 13 is in close contact with the lower end of the folding door 1 in an elastically deformed state.
