The bottom wall 24f of the groove 24a is also used, and the outer peripheral side projection wall is also used as the bottom wall 24i of the groove 24b.
The vertical frame main body 24c does not have a reinforcing member arranged in the hollow portion having a rectangular cross section, and a heating foam material f43 is provided on the indoor side surface of the upper portion of the outdoor side wall 24k over the entire width of the outdoor side wall 24k. are placed.

As shown in FIGS. 3(b) and 4(a), the vertical frame 24 has an end cap 80 made of resin on its upper end. In addition, the vertical frame 24 is also provided with a resin end cap at the lower end.
The end cap 80 is inserted and fixed in the hollow part of the vertical frame body 24c, and includes a vibration-retaining portion 81 that guides the upper rail to prevent the upper part of the inner shoji 20 from swaying, and the door tip side of the vibration-retaining portion 81. It has a drawing portion 82 which is arranged continuously in the groove portion 24b and contacts the drawing piece of the right vertical frame 14 to draw the inner shoji 20 toward the room.

The anti-vibration portion 81 of the end cap 80 has fitting ribs 81a at the left and right ends in the viewing direction on the indoor side surface and the outdoor side surface of the portion inserted into the vertical frame main body 24c. It has an upper wall portion 81c that connects the upper end portions of 81a, 81a. In addition, depending on the case, it is not necessary to provide right and left fitting ribs or the like on the indoor side surface of the anti-vibration portion 81 of the end cap 80 .
Of the fitting ribs 81a, the fitting ribs 81a, 81a formed at least at the right and left end portions in the view direction of the outdoor side surface are formed with missing portions 81b, 81b that are missing in the indoor direction at the lower portions.

Then, the end cap 80 with the anti-vibration portion 81 inserted into the hollow portion of the vertical frame main body 24c is fixed so that the upper end opening of the hollow portion is covered by the upper wall portion 81c.

The heating foam material f43 arranged in the hollow portion of the vertical frame main body 24c has a lower portion f43a having the same dimensions as the exterior dimension of the exterior side wall 24k, and relief portions f43c, f43c at both ends in the dimension direction. It has a formed upper portion f43b.

When arranging the heating foam material f43 on the vertical frame 24, the heating foam material f43 is inserted from the upper opening of the vertical frame main body 24c so that the lower part f43a faces downward, and the heating foam material f43 is attached to the outdoor side wall 24k. , using a fixing means such as double-sided tape.
After that, by inserting the end cap 80 from the upper opening of the vertical frame main body 24c, the upper part of the vertical frame 24 is formed. 4(b), the fitting ribs 81a, 81a do not interfere with the heating foam material f43 fixed to the exterior side wall 24k. Absent.

As shown in FIGS. 4(a) and 4(b), the heating foam material f43 arranged in the hollow portion of the vertical frame 24 has an upper portion f43b which is fitted to the fitting ribs 81a and 81a of the end cap 80 near the upper end of the vertical frame 24, as shown in FIGS. 4(a) and 4(b). 81a, and the lower part f43a is arranged over the entire width of the exterior side wall 24k of the vertical frame main body 24c.

The heating foam material f43 is arranged such that the upper end of the lower portion f43a is positioned above the lower end of the upper rail guided by the anti-vibration portion 81 of the end cap 80, thereby The hollow portion of the vertical frame 24 is opposed to the side surface over the entire length in the width direction.
Further, as shown in FIG. 5, the heating foam material f43 is arranged so that the lower end of f43a of the lower portion is located in a range where the insertion hole of the tapping screw b41 for connecting the upper frame 21 of the vertical frame main body 24c exists. there is

As described above, in the sash of this embodiment, the heating foam material is arranged over the entire width of the indoor side surface of the outdoor side wall (facing wall) at the upper position of the vertical frame in the viewing direction. It is possible to close the space over a wide range of parts.
Then, by forming a missing portion in the fitting rib for inserting the end cap arranged at the upper end of the vertical frame, the heating foam material provided on the outdoor side wall of the vertical frame is It can be arranged over the entire width of the viewing direction up to the range facing the outdoor side of the cap, and foams in the event of a fire to fill the gap between the upper rail guided by the end cap and the vertical stile over the entire width of the vertical stile. can be filled.

In addition, the heating foam material that is arranged over the entire width of the hollow part of the vertical frame is arranged so that the lower end position reaches the insertion hole of the tapping screw for assembling the frame. Since it spreads through the insertion holes of the tapping screws formed in the inner peripheral wall and the outer peripheral wall of the hollow portion of the frame, it is possible to reliably suppress the communication between the indoor and the outdoor at the upper position of the vertical frame.

In addition, the heated foam material expands over the entire width of the vertical frame wall and fills the hollow space. The reinforcing member can be omitted depending on the dimensions of the .

The position of the lower end of the heating foam material arranged in the upper portion of the hollow portion of the vertical frame is not limited to the position of the insertion hole of the tapping screw.
For example, if a hole such as an air introduction hole is formed below and near the insertion hole of the tapping screw, the heating foam material may be arranged up to the position of the hole.
Moreover, the heating foam material arranged near the end of the vertical frame may be arranged not only in the upper part of the vertical frame but also in the lower part of the vertical frame.

As described above, the present embodiment has been described using a sliding window, but the configuration of the sash is not limited at all, such as a double-hung window or a FIX window.
It goes without saying that the above-described embodiments do not limit the invention described in the claims, but are treated as examples.
