Claims (1)

[Scope of utility model registration request] A shoji is attached to a window frame so that it can swing freely about an axis parallel to one side of the window frame, and a threaded rod is supported on the window frame so that it can freely rotate only about the axis. A non-rotatably screwed female screw body and the shoji are connected by a link, and the shoji is swung in both opening and closing directions by the screw movement of the female screw body caused by the rotational drive of the threaded rod. In the opening/closing device, the female threaded body is always moved substantially integrally with the female threaded body by biasing a spring force or the like as the threaded rod rotates, and
The threaded rod connects a driven body capable of rotating while screwing the female threaded body in the window opening direction when movement in the window opening direction is prevented, and one end of the driven body is connected to the shoji. The other end of the link is connected to the window frame, and a movable body is provided on the window frame and moves in a direction perpendicular to a direction in which the shoji approaches and leaves the window frame in conjunction with rotation of the threaded rod, and the movable body and An engaging body that is biased in a protruding direction is attached to one of the shojis, and a pressing portion is formed on the other side to push the engaging body and retract it against the bias just before closing the window. The pressing part prevents the swinging of the shoji in the window opening direction and prevents the movable body from swinging on the engaging body which protrudes when the pressing of the pressing body is released at the same time as the window is closed. 1. An opening/closing device for a swinging window, characterized in that the device engages to allow movement toward the window.
