According to the present invention, as shown in one embodiment, the guide piece 45 may include an elastic piece 48 provided with an engaging portion 48a that engages with the vertical holding plate 24b that constitutes the mounting portion 22. preferable. According to this configuration, the engagement by the engagement portion 48a restricts the attached windshield 4 from being displaced with respect to the vertical holding plate 24b that constitutes the attachment portion 22, so that the windshield 4 is It is possible to suppress falling off from the vertical holding plate 24 b that constitutes the mounting portion 22 . In addition, since the engaging portion 48a is provided on the elastic piece 48, when the windshield plate 4 is attached, the engaging portion 48a can suppress the generation of a force acting as a resistance to the attachment. Therefore, the detachment of the windshield plate 4 can be suppressed while maintaining the ease of attachment of the windshield plate 4 .

In the present invention, as shown in one embodiment, it is preferable that the engaging portion 48a is a projection. According to this configuration, not only is it possible to simplify the configuration of the locking portion 48a, but only by providing a hole or a recess in the vertical holding plate 24b that constitutes the attachment portion 22, the wind when the windshield plate 4 is attached can be prevented. This makes it possible to position the stop plate 4 and to further suppress the occurrence of a force that acts as resistance when the wind stop plate 4 is attached.

In the present invention, as shown in one embodiment, it is preferable that the elastic piece 48 is cantilevered from the other end side, which is the tip side of the guide piece 45 . According to this configuration, even if a large force is applied to the windshield plate 4 when the windshield plate 4 is attached, the force applied to the locking portion provided on the elastic piece 48 is reduced due to the cantilever structure. In addition, since the locking portion (projection) 48a is provided on the end portion side (the other end portion side) of the elastic piece 48 on the side of the plate-like portion 47, sliding of the windshield plate 4 is engaged at an initial stage. The stopping portion 48a does not act as a resistance, and is locked in the through hole 24e at the stage when the slide is finished. Therefore, since excessive force is not applied to the cantilever portion (base) of the elastic piece 48, damage to the elastic piece 48 and the locking portion 48a when the windshield plate 4 is attached can be suppressed.

In the present invention, as shown in one embodiment, when the sash is required to have fireproof performance, it is preferable that the windshield plate 4 is attached with a heating foam material. According to this configuration, even if the windshield plate 4 is melted and lost due to fire, it is possible to prevent the fire from reaching the room by foaming with the heated foaming material. In particular, as shown in one embodiment of FIGS. 1 to 7, by providing the lower surface 46a of the mounting portion 46 of the windshield 4 and the second side surface 46d of the mounting portion 46, the fire reaches the room. The heating foam material can be foamed in the path, and it is possible to further suppress the fire from reaching the room. Specifically, since the heating foam material 43 faces the projecting horizontal plate 23 of the lower frame 2b and the outdoor surface of the inner and lower rails 18, the lower frame made of aluminum alloy senses the heat raised to a high temperature by the flame. It is easy and the heating foaming material 43 can be foamed at an early stage.

In the present invention, as shown in one embodiment, it is preferable that the leading end (the other end) of the guide piece 45 is provided with a raised portion 45a extending toward the lower surface 46a of the mounting portion 46 . .

As shown in FIGS. 10 to 12, in the sash 1 of the modified example, a heating foam member 61 is provided on the outdoor side surface of the indoor-side intermediate vertical plate 14 at a position where the windshield plate 4 is attached. Moreover, in the sash 1 of the modified example, a heating foam material 62 is provided along the inside of the outer airtight material holding portion 24 . Furthermore, a heated foam material 63 is provided on the inner surface of the meeting frame 6e of the inner shoji 6 as well. By providing these heating foam materials 61 to 63, the fireproof performance of the sash can be further improved. It goes without saying that each frame of the sash and each frame of the outer shoji 5 and the inner shoji 6 may be provided with other heating foam material.

FIG. 13 is a diagram schematically showing the configuration of the cross section in the vertical direction of the lower frame of the sash frame of the sash according to another modification to which the anti-vibration fitting 64 is attached, and the lower frame of the outer and inner shoji. 14 is a diagram showing the mounting state of the anti-vibration metal fitting 64, and FIG. As shown in FIGS. 13 to 15, the anti-vibration metal fittings 64 are provided on the inner shoji 6 to prevent the inner shoji 6 from shaking in the closed state and the running state. In this embodiment, the anti-vibration metal fitting is made of a main body portion 64a made of polypropylene and an elastomer such as rubber or vinyl provided on the lower part and the outside of the main body portion 64a. and an elastic portion 64b. A heating foam material 64c is provided on the upper surface of the body portion 64a. Moreover, the side surface of the sash 2 in the lateral direction of the body portion 64a is also provided with a heating foam material 64c. It should be noted that the body portion 64a and the elastic portion 64b are also preferably made of a flame-retardant material (e.g., equivalent to UL94 V-0) like the windshield plate 4.
By adopting the anti-vibration fitting 64 having such a configuration, it is possible to improve the fireproof performance of the sash while preventing the inner shoji 6 from swaying in the closed state and in the running state.
