ABSTRACT:
The folding doors 100 includes of a first door panel 150 and a second door panel 110, the first door panel 150 being attached to the door opening portion of the wall rotatively by a pin 150. The second door panel 110 is attached to the first door panel 150 by a hinge 4. A guiding device 120 is mounted on the upper portion of the second door panel 110. The guiding device 120 holds a slider 122 and a rotary damper 200 for damping the rotation of the axis holding the slider. The slider 122 slides without rotating inside the guiding rail mounted on the upper portion of the door opening portion. The second door panel 110 rotates by opening/closing action, so by damping this relative rotation with the rotary damper 200, the folding doors could be closed quietly.
