1. At least one of the hanger 20 or the roller 22 is in contact with the stopper 4 provided at the lower end of the guide rail 1 and is stable. Due to the weight of the door 10, the door 10 does not open unnecessarily unless an external force is applied. When a force is applied in the direction in which the door 10 is opened, the pair of rollers 22 and 23 rolls on the guide rail 1, and the door 10 moves in the opening direction while maintaining the vertical posture, and with the inclination of the guide rail 1, It rises slightly gradually. When the door 10 is fully opened, in the first embodiment, the lower roller 22 is fitted into the temporary locking recess 4, and the door is temporarily stopped at that position and does not close naturally.

Roller bearing member 2 so that door 10 maintains a vertical posture.
The positions of the slits 6 and 27 in the respective slits 24 and 25 are determined and fixed. For example, it is fixed by the second bolt 28 as in the embodiment. By doing so, the door 10 always keeps a vertical position, and no unnecessary moment is generated.
Distortion due to fatigue of each part does not occur.

There is only a simple tensile load due to its own weight, no rotational moment acts, and there is no danger of these becoming fatigued and distorted during long-term use. Further, since the door is closed by its own weight, there is no possibility that the door 30 remains open, and no driving device is required. According to the second aspect of the present invention, in addition to the effects described above, the height positions of the rollers 22 and 23 can be adjusted according to the inclination angle of the guide rail 1, and can be adjusted to a completely closed state. In the embodiment, the guide rail is provided with the temporary locking recess 4 into which only the lower roller 22 fits when the door 30 is fully opened, so that the temporary door 1 can be temporarily closed while a forklift or other cargo handling vehicle passes.
0 can be kept open, which is very convenient.
