Claims

[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 biased by a spring force or the like so that it moves substantially integrally with the female threaded body, and when movement in the window closing direction is prevented, only the female threaded body is moved. A driven body is connected to the driven body so as to be able to spiral in the window closing direction, one end of the link is connected to the shoji, and the other end of the link is connected to the driven body, and the female screw body and the shoji are connected to each other. A pair of engaging portions are formed that engage with each other as the female screw body spirals in the window closing direction after contacting the window frame and prevents the shoji from swinging in the window opening direction. An opening/closing device for swinging opening/closing windows.
