Effects of the invention As described above, in the present invention, when the shoji is closed, the outer shoji pulling piece enters into the notch provided in the chimney return of the outer shoji, and when the handle is then locked, the slider moves up and down. Then, the sloped surface of the outer shoji pulling piece engages with the engaging part of the recess formed in the chimney return of the outer shoji, and the connecting frames of the inner and outer shoji are pulled together by a wedge action, and the inner shoji drawing mechanism Since the inner shoji is pulled closer to the inner shoji, the inner and outer shoji can be strongly pulled together by the wedge action of the sloped surface of the outer shoji pulling piece, and the amount of pulling can be reduced. It can be made larger. In addition, since the outer shoji pulling piece is attached to the slider so that its position can be adjusted and connected to the slider, there is no need for a mechanism to exchange and transmit the vertical movement of the slider to movements other than the vertical movement to the outer shoji pulling piece, making it extremely simple. It has the advantage that it can be made into a simple mechanism, which can reduce failures, and that the amount of pulling by the outer shoji pulling pieces can be easily adjusted. In addition, the edge of the recess in the outer shoji closing direction is made into a locking part, and the side surface of the sloped surface part of the outer shoji drawing piece is provided with a locking surface that can be engaged with the locking part, so when the shoji is closed and drawn. Even if an attempt is made to open the inner or outer shoji, opening of the inner or outer shoji will be prevented by the engagement of the locking part of the outer shoji and the locking surface of the outer shoji pull piece, in addition to the normal locking with crescents, etc. This has the effect of significantly improving the security effect.
