The present invention was created in order to solve the above-mentioned drawbacks, and the purpose thereof is to simply perform a simple process on the hanger roller, and the traveling wheels always rotate smoothly. Then, even if it is a folding door with a large number of panels, it is intended to provide a laterally-folding folding door that can be smoothly opened and closed with a light force.

[0004]

In order to solve the above problems, the technical means taken by the present invention is a hanger in which a plurality of panels laterally connected through a joint portion are provided in the joint portion. In a folding door that is suspended by a roller so as to be foldable freely, the running wheels of a hanger roller that runs along the above-mentioned upper rail are respectively moved up and down with respect to their rotational axes. It is characterized by being configured so that it can be rocked to the left and right.

[0005]

Therefore, according to the present invention, a hanger roller is used.
By pulling the folding door suspended on the upper rail in the horizontal direction, a plurality of panels connected via the joint part,
If you move along the upper rail to close the opening and push the folding door to one side of the upper rail, the multiple panels will be folded and folded from the joint to open the opening. Open. And even if the running wheel of the hanger roller and the upper rail may not be parallel during the above-mentioned opening and closing operation,
Since the running wheels are transformed vertically and horizontally with respect to the rotation axis and rotate along the upper rail, the folding door can be smoothly opened and closed with a light force.
