The folding member 2 is accommodated in the recess of the door main body 1 by contacting the door stop 19 hanging over its entire length so that a stable closing operation can be obtained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The door body 1 has a wide width, and the surface thereof has a decorative finish. A folding body 2 having a width approximately half that of the door body 1 is pivotally connected by a hinge 3 to the back surface of the door body 1 at a substantially central portion in the width direction so as to be foldable, and the door body 1 and the folding body 2 are connected.
The hinges 3 can be folded like a double-folded door. The folding body 2 can be inserted into the recess 9 formed on the back surface of the door body 1 so as to be substantially flush therewith. Rotational running supports 6, 6 that rotate with respect to the upper and lower rails 4 and 5 are provided at the front end of the folding body 2 and the end of the door body 1 on the door tip side. As shown in FIG. 1, the rotary traveling support tool 6 is mainly composed of a pivot 7 for pivotal support and a runner 8 mainly for traveling, and the pivot 7 is supported by a lower end of the folding body 2 and a door body. 1 and the runner 8 is formed so as to project to the upper surface of the front end of the folding body 2 and the upper surface of the door body 1 on the door end side. The runner 8 is provided with a runner block 11 having a runner roller 10 rotatably provided coaxially with the shaft 12 of the pivot 7 so as to be rotatable relative to the runner shaft 17. A pivot hole (not shown) is formed near the vertical frame 15 of the lower rail 5. Then, the runner rollers 10 of the door body 1 and the folding body 2 are rotatably mounted on the receiving piece 16 of the upper rail 4, and the pivots 7 of the door body 1 and the folding body 2 are inserted so that the lower rail 5 can travel. I am doing it. By the way, as shown in FIG. 1, a door stop 19 is provided on the side of the upper rail 4 so as to hang down the entire length of the upper rail 4 and contact the back surface of the folded body 2 housed in the door body 1 and the recess 9.
