Since the shoji retaining member 7 is attached to the lower ends 212a and 213a of the frame downward projecting rail 213), the shoji retaining member 7 becomes an obstacle and the shoji (inner shoji 3 and outer shoji 4) becomes the window frame 2. It can be prevented from coming off from.

In the present embodiment, the shoji retaining member 7 is arranged with shoji (inner shoji 3, outer shoji 4) on the lower projecting rail (upper frame downward projecting rail 212 for internal shoji, upper frame downward projecting rail 213 for external shoji). In a position where the shoji (inner shoji 3, outer shoji 4) can be slid and placed, the lower protruding rail (upper frame lower protruding rail 212 for inner shoji, lower upper frame for outer shoji) It is fixed to the lower end portions 212a and 213a of the protruding rail 213). As a result, when the shoji (inner shoji 3, outer shoji 4) is placed at the position where the shoji retaining member 7 is fixed, the shoji retaining member 7 becomes more obstructive and the shoji (inner shoji 3, outer) becomes more obstructive. The shoji 4) is more difficult to come off from the window frame 2. Further, at a position where the shoji (inner shoji 3, outer shoji 4) is not arranged, the shoji retaining member 7 is provided with a downward projecting rail (upper frame downward projecting rail 212 for internal shoji, upper frame downward projecting rail 213 for external shoji). ) Can be easily attached.

In the present embodiment, the shoji retaining member 7 has a predetermined length in the left-right direction in which the downward projecting rail (upper frame downward projecting rail 212 for internal obstacles, upper frame downward projecting rail 213 for external obstacles) extends. The end portion of the shoji retaining member 7 in the left-right direction is formed in a tapered shape toward the outside in the left-right direction. This makes it possible to ensure safety when a person touches it. Further, since the shoji shoji retaining member 7 is moved by scraping the recess 631 of the engaging packing plate 63 of the steady rest member 6, the internal shoji 3 or the external shoji 4 can be smoothly moved.

The present disclosure is not limited to the above embodiment, and modifications, improvements, etc. to the extent that the object of the present disclosure can be achieved are included in the present disclosure.

For example, in the above-described embodiment, the shoji retaining member 7 (rail extension member) is provided on the inner shoji upper frame downward projecting rail 212 that guides the sliding movement of the inner shoji 3, and the sliding movement of the outer shoji 4 is guided. Two are provided on the lower protruding rail 213 of the upper frame for the external shoji. However, the number and position of the shoji retaining member 7 (rail extension member) is not limited to this embodiment. Further, it may be provided only on one of the internal shoji 3 and the external shoji 4.

In the above-described embodiment, the shoji retaining member 7 (rail extension member) is screwed to the inner shoji upper frame downward protruding rail 212 (lower protruding rail) or the outer shoji upper frame downward protruding rail 213 (downward protruding rail). ), But not limited to this. For example, the shoji shoji retaining member 7 (rail extension member) is fixed by sandwiching the upper frame downward projecting rail 212 (downward projecting rail) for internal shoji or the upper frame downward projecting rail 213 (lower projecting rail) for external shoji. Alternatively, the engaging portion provided on the shoji retaining member 7 (rail extension member) may be provided with the upper frame downward protruding rail 212 (downward protruding rail) for the internal shoji or the upper frame downward protruding rail 213 (downward protruding rail) for the shoji. ) May be fixed to a notch (engaged portion), a hole (engaged portion), or the like.

In the above embodiment, the window frame 2 of the inner window 1 is made of a resin frame, but the present invention is not limited to this. The window frame of the inner window 1 may be made of, for example, a metal frame.
