Even when the warpage of the door-side vertical frame due to the temperature difference between the inside and outside of the room increases due to the guide portion of the second door-stop piece, the portion of the door-side vertical frame closest to the vertical frame is closed when the shoji is closed. Because it can contact the guide part of the piece per two houses,
Regardless of the warping deformation of the shoji due to the temperature difference between the indoor and the outside, the shoji can be securely closed, the warping of the entire shoji can be reduced, and the locking can be reliably performed. These damages can be prevented by preventing collision between the frame and the vertical frame.
