A space between the outer heat insulating material filling portion 43 c and the inner heat insulating material filling portion 44 d provided in the indoor portion 44 is filled with the heat insulating material 45 . As is clear from the drawing, in the present embodiment, the outer substrate portion 43a and the outer heat insulating material filling portion 43c together with the lower horizontal plate portion 43d and the outer vertical plate portion 43e form a substantially square hollow portion. The outdoor side portion 43 is configured so as to do so. A screw hole 43f is provided in a portion of the lower surface of the outer substrate portion 43a slightly biased toward the outdoor side. The outer rail portion 45A is a thin plate projecting upward from a position corresponding to the screw hole 43f on the upper surface of the outer substrate portion 43a, and is configured to have substantially the same protrusion height as the inner rail portion 45B. I have At the upper edge of the outer rail portion 45A, similarly to the inner rail portion 45B, a bulging portion 43g having a large plate thickness is provided so as to protrude toward the interior of the room. The outer support plate portion 43b protrudes substantially horizontally toward the outside of the room from the edge of the outer substrate portion 43a on the outdoor side, and then extends upward by bending at a substantially right angle. The protrusion height of the outer support plate portion 43b is configured to be smaller than the protrusion height of the outer rail portion 45A.

An inner lower frame cover member 51, an outer lower frame cover member 52, and a screen door rail constituent member 53 are attached to the lower frame 12 having the above structure. The inner lower frame cover member 51 is arranged between the inner rail portion 45B and the inner side plate portion 44b on the upper surface of the inner base plate portion 44a so that the inner rail portion 45B and the inner side plate portion 44b are arranged. 44b to narrow the opening width. The inner lower frame cover member 51 is configured to have substantially the same protrusion height as the inner rail portion 45B when arranged on the upper surface of the inner substrate portion 44a. A gap is provided between the inner lower frame cover member 51 and the inner rail portion 45B so that the inner shoji 20B can be moved. The outer lower frame cover member 52 is disposed on the upper surface of the outer board portion 43a on the inner side of the room than the outer rail portion 45A, thereby providing a space between the inner rail portion 45B and the outer rail portion 45A. It is for narrowing the opening width of the The outer lower frame cover member 52 is configured to have substantially the same protrusion height as the outer rail portion 45A when arranged on the upper surface of the outer substrate portion 43a. Between the outer lower frame cover member 52 and the inner rail portion 45B, and between the outer lower frame cover member 52 and the outer rail portion 45A, gaps are secured to allow the outer shoji 20A to be moved. There is. The screen door rail constituent member 53 is disposed between the outer rail portion 45A and the outer support plate portion 43b in the outdoor side portion 43, so that a gap between the outer rail portion 45A and the outer support plate portion 43b is provided. This is for narrowing the gap and providing the screen door rail portion 53 a on the lower frame 12 . Between the screen door rail constituent member 53 and the outer rail portion 45A, a gap is secured to allow the movement of the outer shoji 20A. Although not shown in the drawings, the lengthwise dimension of the inner lower frame cover member 51 and the outer lower frame cover member 52 can be adjusted so that a stopper member 60, which will be described later, can be arranged on the upper surface of the lower frame 12. As shown in FIG. The dimension along the length of the screen door rail component member 53 is larger than the inner lower frame cover member 51 and the outer lower frame cover member 52, so that it can be arranged between the left and right vertical frames 13, 14 without gaps. is set to

Furthermore, as shown in FIGS. 5 to 10, the lower frame 12 is provided with a notch 46 at the end located on the left side of the inner rail portion 45B as seen from the room interior. A stopper member 60 is provided on the upper surface of the lower frame 12 so as to cover it.

The notch portion 46 is provided at a portion separated from the left vertical frame 13 so that a part of the inner rail portion 45B remains between it and the left vertical frame 13, and is opened above the inner rail portion 45B. , the space between the inner rail portion 45B and the inner side plate portion 44b and the space between the inner rail portion 45B and the outer rail portion 45A are communicated with each other along the projection direction. It penetrates 45B. In the present embodiment, the right edge portion 46a of the inner rail portion 45B located on the right side and the left edge portion 46b of the inner rail portion 45B located on the left side when viewed from the inside of the room are vertically aligned with each other. A rectangular notch 46 is formed in the inner rail portion 45B so as to be parallel. The right edge portion 46a of the inner rail portion 45B located on the right side of the notch portion 46 is provided at a position where the distance to the vertical frame cover member 41 attached to the left vertical frame 13 is larger than the projecting dimension of the crescent 26B. .

The stopper member 60 restricts the movement of the inner shoji 20B with respect to the frame 10 by coming into contact with the inner sash 24B when the inner shoji 20B is moved to the left as viewed from the inside of the room. In this embodiment, a stopper member 60 made of resin, in which a first contact portion 61, a second contact portion 62, and a connecting portion 63 are integrally formed, is applied.

The first contact portion 61 is arranged in the space between the inner side plate portion 44b and the inner side rail portion 45B on the interior side of the room. The second contact portion 62 is disposed in a space between the outer rail portion 45A and the inner rail portion 45B on the outside of the vehicle. The first contact portion 61 and the second contact portion 62 have the same dimension along the length of the lower frame 12 . The longitudinal dimension of the first contact portion 61 and the second contact portion 62 is set to be slightly smaller than the distance from the right edge portion 46a of the inner rail portion 45B to the left vertical frame 13. be. The vertical dimensions of the first contact portion 61 and the second contact portion 62 are configured such that the other end portion is larger than the one end portion close to the left vertical frame 13 . Specifically, when the stopper member 60 is arranged on the upper surface of the lower frame 12, one end of each of the first contact portion 61 and the second contact portion 62 is located at the uppermost end of the inner rail portion 45B. The vertical dimension is set so that it is almost the same as the upper end position. The case where the stopper member 60 is arranged on the upper surface of the lower frame 12 means that, as shown in FIG. The lower surface of the second contact portion 62 is in contact with the upper surface of the outer substrate portion 43a. When the stopper member 60 is arranged on the upper surface of the lower frame 12, the other end portions of the first contact portion 61 and the second contact portion 62 have the same uppermost end position as the upper end position of the inner rail portion 45B. Alternatively, the vertical dimension is set so as to protrude slightly beyond the upper end position of the inner rail portion 45B.

The connecting portion 63 connects the other end portion of the first contact portion 61 and the other end portion of the second contact portion 62 . In FIGS. 7 to 9, the connecting portion 63 is clearly indicated by dots for the sake of convenience. The connecting portion 63 has a dimension along the longitudinal direction of the lower frame 12 and a vertical dimension so that the stopper member 60 can be inserted into the notch portion 46 of the inner rail portion 45B when the stopper member 60 is arranged on the upper surface of the lower frame 12. Each dimension is set. The connecting portion 63 is provided with a passage groove portion 63a on the end surface facing the right edge portion 46a of the inner rail portion 45B, in other words, on the end surface on the side where the inner shoji 20B abuts. The passage groove portion 63a is a vertically elongated notch that opens to the end surface of the inner rail portion 45B facing the right edge portion 46a and the lower surface of the connecting portion 63, and has a dimension along the projection direction that allows the inner rail portion 45B to pass therethrough. It is formed in the size that can be done. The vertical dimension of the passage groove portion 63a is set slightly lower than the inner rail portion 45B when the stopper member 60 is arranged on the upper surface of the lower frame 12. As shown in FIG. Therefore, when one end of the stopper member 60 is kept in contact with the upper surface of the lower frame 12 and the other end is lifted upward, the inner rail portion 45B can be passed through the passage groove portion 63a. is.

Further, the stopper member 60 is provided with an engaging portion 61a. The engaging portion 61 a is provided on the upper edge portion of the first contact portion 61 closer to the left vertical frame 13 than the connecting portion 63 and protrudes toward the second contact portion 62 . When the stopper member 60 is arranged on the upper surface of the lower frame 12, the engaging portion 61a abuts on the bulging portion 43g of the inner rail portion 45B from the lower side. It functions to restrict movement to In the present embodiment, two engaging portions 61a are provided separately from each other in a portion adjacent to the connecting portion 63 and a portion adjacent to the left vertical frame 13, respectively.

In the fittings constructed as described above, when the stopper member 60 is arranged on the upper surface of the lower frame 12, a dimension larger than the projecting dimension of the crescent 26B from the projected surface of the vertical frame cover member 41 attached to the left vertical frame 13 is secured. The end surface of the stopper member 60 is placed at the position. Therefore, even when the inner shoji 20B is vigorously moved toward the left vertical frame 13, the inner fitting frame 24B contacts the stopper member 60 before the crescent 26B collides with the left vertical frame 13. Movement is blocked, and the collision of the crescent 26B with the left vertical frame 13 can be prevented.

Moreover, since the connecting portion 63 that connects the first contact portion 61 and the second contact portion 62 of the stopper member 60 passes only through the notch portion 46 provided in the inner rail portion 45B, the connection The portion 63 does not overlap the inner rail portion 45B. Therefore, without increasing the projecting dimension from the inner rail portion 45B, it is possible to secure a sufficient plate thickness for the connecting portion 63 at the notch portion 46 and improve the strength, and the inner shoji 20B repeatedly hits. There is no risk of early damage to the stopper member 60 even when it comes into contact with it. In addition, it is possible to prevent the stopper member 60 from protruding from the lower frame 12, and it becomes easy to form the upper surface of the lower frame 12 in a flat shape with little unevenness, making it easy to make fittings barrier-free.

Furthermore, since a portion of the inner rail portion 45B is left at a portion closer to the left vertical frame 13 than the notch portion 46, the impact force applied to the stopper member 60 by the contact of the inner shoji 20B is reduced to the left side. Since it is transmitted to the inner rail portion 45B via the edge portion 46b, there is no risk of direct transmission to the left vertical frame 13. This eliminates the possibility that the mounting screws (not shown) threaded from the left vertical frame 13 into the screw holes 44e and 43f of the lower frame 12 are loosened to create a gap between them.

Further, since one end of the stopper member 60 extends to a position facing the lower end surface of the vertical frame cover member 41, the lower frame 12 can be simply formed directly into the lower end surface of the vertical frame cover member 41. Therefore, the vertical frame cover member 41 does not require complicated processing, and the appearance quality can be improved.

Moreover, since the stopper member 60 is provided with the passage groove portion 63a on the end face facing the inner rail portion 45B, the vertical frame cover member 41 facing one end portion of the stopper member 60 is attached to the left vertical frame 13. It is possible to attach and detach the stopper member 60 with respect to the lower frame 12 even if it is still in place. That is, even when the other end of the stopper member 60 is lifted upward while the other end of the stopper member 60 is in contact with the lower frame 12 to assume an inclined posture, the inner rail portion 45B passes through the passage groove portion 63a. The stopper member 60 does not interfere with the inner rail portion 45B. Therefore, by setting the stopper member 60 in an inclined posture, one end of the stopper member 60 can be moved in and out of the portion facing the end surface of the vertical frame cover member 41 . As a result, the stopper member 60 can be attached and detached without removing the vertical frame cover member 41 from the left vertical frame 13, and the stopper member 60 can be easily replaced.

In the above-described embodiment, a double sliding window is exemplified. It can also be applied to the bottom frame. Moreover, although the double sliding window is configured so that the right side as viewed from the inside of the room serves as an inner shoji, the left side may serve as an inner shoji. Furthermore, although the lower frame is exemplified by connecting the outdoor-side portion and the indoor-side portion with a heat insulating material, the lower frame does not necessarily have to be provided with the heat insulating material.

Further, in the above-described embodiment, the inner rail portion, the inner side plate portion, and the outer rail portion are configured to have substantially the same height, and the inner lower frame cover member and the outer lower frame are mounted on the upper surface of the lower frame. Although the cover member and the screen door rail constituent member are attached, the present invention is not limited to these.

Furthermore, in the above-described embodiment, the notch is provided so as to leave the rail portion between it and one of the vertical frames (left vertical frame 13). It is not necessary to leave a rail portion between the vertical frame. Furthermore, it is not always necessary to provide a vertical frame cover member as one of the vertical frames, and in this case, it is not necessary to provide a passage groove in the stopper member. Furthermore, the stopper member does not necessarily have to have an engaging portion.
