When the flexible strip 14 is simply driven in circulation in one direction by a manual drive device, each pressing member 15 corresponding to the lower arm 3 and the upper arm 5 is moved by the flexible strip 14, and each pressing member 15 is moved by the flexible strip 14. Part 1
5 engages with the pressure receiving part 6 for protrusion and rotation of each arm 3, 5 to rotate each arm 3, 5 in the arm tip protrusion direction, and also moves the flexible strip 14 in the other direction simply by a manual drive device. When the lower arm 3 and the upper arm 5 are rotated by the flexible strip 14,
While each pressing member 15 corresponding to is moved,
Since each pressing member 15 engages with the retraction rotation pressure receiving part 7 of each arm 3, 5 and rotates each arm 3, 5 in the arm tip retraction direction, the lower arm 3 and the upper arm 5 in the arm tip protrusion direction and the arm tip retraction direction, and a lower guide member 9 attached to the tip of the lower arm 3.
The upper guide member 10 attached to the tip of the upper arm 5 can be protruded from inside the sash frame 1 to the outdoor side or housed inside the sash frame 1, and the lower guide member 9 and the upper guide member 10 protruding from inside the sash frame 1 to the outside of the room, the shoji door 8 can be guided by the lower guide member 9 and the upper guide member 10 and moved laterally, and the shoji door 8 can be moved laterally by the lower guide member 9 and the upper guide member 10. By rotating each arm 3, 5 in the retracting direction while disposed at the center of the upper guide member 10, the lower guide member 9, the upper guide member 10, and the shoji door 8 supported by these can be moved. The shoji door 8 can be easily closed into a window shape by being pulled into the sash frame 1 from the outside of the room and fitting the shoji door 8.

In addition, especially in the case of the present invention, there is no need to use an expensive lower driven gear and an upper driven gear having a large number of arcuate teeth, and a simple-shaped, inexpensive gear having a pressure receiving part 6 for protruding rotation and a pressure receiving part 7 for retracting rotation is used. Since the lower arm 3 and upper arm 5 can be used, it is possible to manufacture a protruding horizontal sliding window that can be changed to a window-like appearance at a low cost, and the lower arm 3 and upper arm 5 are flexible. Since the strip 14 does not rub against each other, the flexible strip 14 can be moved with a light force, and wear of the flexible strip 14 can be prevented.
