Furthermore, the door includes a central control part 2 having a rotation plate 21, and three direction ropes 31, 32, 33 which connect the rotation plate 21 and each of the upper rail 11, the lower rail 12, and the door end rail 13, respectively. Through rotating the rotation plate 21, the ropes 31, 32, 33 are pulled, resulting in that the upper rail 11, the lower rail 12, and the door end rail 13 can be drawn to the door center direction.SELECTED DRAWING: Figure 2
