FIGS. 2A to 2C show a guide rail 1a attached to the upper frame 1 and a bearing member 21 attached to the guide rail 1a. FIG. 2c shows a sectional view of the guide rail 1a.
Has a groove 31 for receiving the bearing member 21, and a pair of protrusions 33 protrude in the groove 31.

The bearing member 21 is, as shown in FIG.
An L-shaped fixture 22 and a screw 23
And a resin-made bearing portion 24 connected via a. The bearing member 21 is inserted into the groove 3 of the guide rail 1a.
1, the screw 23 is loosened and the fixing bracket 2 is inserted.
A gap 25 is formed between the bearing 2 and the bearing portion 24, and the projection 33 of the groove 31 is sandwiched in the gap 25, and then the entire bearing member 21 is pushed in the direction of arrow A. As shown in FIGS. 2B and 2C, a notch 35 is formed in the top plate of the guide rail 1a. The upright portion 22a of the fixing bracket 22 is engaged. This standing part 22a
Defines the permissible distance for the entire bearing member 21 to move in the direction of arrow A, and the upright portion 22a has the notch 3
If it contacts the side 35a of No. 5, the sliding movement over a longer distance is restricted.

As shown in FIGS. 2A and 2B, the lower surface of the bearing portion 24 made of resin has an inclined surface 27a and the inclined surface 2a.
A horizontal surface 27b continuous with 7a and a receiving hole 27c continuous with the horizontal surface 27b are formed.

Next, referring to FIG.
The procedure for suspending the folding door 5 between a and 2a will be described. FIG.
3A, the upper pivot shaft 9 is urged upward by the spring force of a spring (not shown).
