The runners R, R are rotatably provided around an axis and mounted on the upper suspension rail 2 having an L-shaped cross section so that the runners can be suspended and run. A guided groove 8 is formed on the lower surface of the door 1. The lower traveling guide 3 is attached to the lower frame 9 in a substantially L-shape. More specifically, the lower travel guide 3 is provided substantially at the center of the opening / closing stroke of the door 1 so that the lower travel guide 3 is inserted into the guided groove 8 even at the open position and the closed position of the door 1. Have been.

As described above, the lower travel guide 3 is narrow in the guide direction, and the lower travel guide 3 is moved by the opening / closing stroke of the door 1 so that the lower travel guide 3 is held by the lower travel guide 3 even at the open position and the closed position of the door 1. substantially in <br/> provided that in the central portion, while always guide can stably travel the door 1 under running guide 3, the lower running guide 3 provided at a substantially central portion of the closing stroke, the conventional As described above, the appearance is greatly improved as compared with the case in which the lower traveling guide 3 is provided over substantially the entire length of the opening / closing stroke. In the figure, X is the rotation locus of the door 1, and 10 is the entrance.

The door 1 is formed in an arc shape. When the door 1 is formed in an arc shape, the tip of the door 1 tends to swing inward in the radial direction of the door 1 due to the impact at the opening / closing end position, but such a point is avoided. It is. In other words, as shown in FIG. 3A, the lower traveling guide 3 is divided into a plurality of inner and outer guides 4 and 5 formed by the inner and outer walls of the guided groove 8 on the door 1 side. The inner and outer guides 4 and 5 can be brought into contact with each other.

As described above, the inner and outer cover guides 4 and 5 of the arc-shaped door 1 are also guided by the divided lower traveling guide 3 so that the arc-shaped door 1 is impacted at the opening / closing end position. Thus, it can be prevented from being swung in the radial direction. And like this,
The lower traveling guide 3 is divided into a plurality of parts, and one lower traveling guide 3a is provided at a position where the lower traveling guide 3a slightly projects from the guided groove 8, so that the traveling guide of the arc-shaped door 1 can be sufficiently performed. In order to move the door 1 in the direction of arrow a in FIG. 4 , the end of the door 1 collides with the point B of the lower travel guide 3a, and the start of the door 1 is obstructed. I have. That is, FIG.
As shown in (c), when the tip of the inner or outer guide 5 is bent to the side away from the lower running guide 3a at the end, and the door 1 is run in an arc from the open / close end to the opposite side. In addition, the opening and closing operation can be performed smoothly by avoiding violent collision with the eccentric lower traveling guide 3a.

FIG . 6 shows a place where the above-mentioned arc-shaped door 1 is installed, that is, a shower room. It goes without saying that the location where the door 1 is provided can be variously changed.
