2. Description of the Related Art As shown in Japanese Utility Model Publication No. 3-49269, a conventional moving device for shoji screens has four operating rods provided inside the frame of the shoji screen and is operated by operating a handle provided on the shoji screen. The operating rod is adapted to move linearly, and the sliding door is translated inward while the link is rotated by the guide hole for converting the linear motion into the rotational motion and the operating pin fitted in the guide hole.

[0003]

According to the above-mentioned structure, when the sliding door is moved in parallel from the closed state on the same plane to the room side by the rotation of the link, the connecting frame shaft is rotatable between the sliding door and the link. Rotates around the axis of the roller, so that the shoji moving toward the room also has the same trajectory as the pivot.

For this reason, a shoji having a very large thickness has a structure in which two sheet glasses are fitted on the inside and the outside of the room or a blind is incorporated in the space between the two sheet glasses. The vertical frame of the shoji collides with the frame while moving to the indoor side. That is, there is a problem that the shoji is limited in thickness.

Further, when the shoji screen is moved to the indoor side and opened in a sliding shape along the rail, since the shoji screen does not have a steady rest, the shoji screen moves in the outdoor direction to prevent smooth opening and closing. However, there was also a problem that the conversion part of the rotational movement is easily broken.

Therefore, the object of the present invention is to prevent the vertical frame of the shoji from colliding with the frame body even when the shoji having a large thickness is moved to the indoor side, and to make the shoji moving to the indoor side into a sliding shape. It is an object of the present invention to provide a moving device for a sliding sliding door, which is designed to stop the swinging of the sliding door when opened.
