Support brackets (not shown) are provided on the right side of the upper end of the folding door constituent member 7 on the left and right sides, and a rotating shaft 10 whose axis is directed vertically is rotatably provided on these supporting brackets. A roller support 11 is provided on the roller support 10, and a pair of left and right rollers 12 is provided on each of the roller supports 11 so that a total of four rollers 12 are directed in the front-rear direction. These rollers are provided rotatably.
12 is mounted on the upper surface of the horizontal wall 13 before and after the upper guide rail 3.

The lower guide rail 4 is fixed to the floor 18 by a known fixing means such as a screw (not shown) or an adhesive. Further, a pin guide groove (not shown) extending in the left-right direction is formed in the lower guide rail 4.

The lower left and right sides of the folding door 6, that is, the lower left side of the left folding door component 7 and the lower right side of the right folding door component 7 are concentric with the axis of the rotary shaft 10. The pins 20 are projected downward as described above,
Are fitted in a pin guide groove (not shown) of the lower guide rail 4 so as to be movable left and right. With the above configuration,
The folding door 6 is configured such that the left and right folding door constituting members 7 have V
It opens by folding in the shape of a letter.

The pair of left and right folding door constituting members 7 are connected by hinges 8 so that a gap 22 is formed between the two in a closed state. The gap 22 has a lateral width into which a finger such as a thumb or an index finger enters.

A movable cover 24 made of a synthetic resin, metal, or the like having a U-shaped horizontal cross section is covered on the edge of the hinge 8 side of each of the folding door components 7. The movable cover 24 covers the edge of the front surface of the folding door component 7 and covers the gap 22 in a state where the folding door component 7 is closed;
A side surface covering portion 26 connected to the cover body 25 facing the side surface of the folding door component member 7, and a rear surface covering the edge of the rear surface of the folding door component member 7 connected to the side surface covering portion 26; And a cover portion 27. A notch is formed in the rear cover 27 so as to escape the hinge 8 (to prevent collision and interference with the hinge 8) (see FIGS. 2 and 3).
The gap 22 is concealed by the cooperation of the left and right covering members 25.
