The vertical stile body 24c is composed of a hollow portion having a rectangular cross section having an inner peripheral side prospective wall and an outer peripheral side prospective wall, an indoor side mitsuke wall 24j, and an outdoor side mitsuke wall 24k, and the inner peripheral side prospective wall is a panel frontage. The bottom wall 24f of the 24a is also used, and the outer peripheral side prospective wall is also used as the bottom wall 24i of the groove portion 24b.
The vertical stile body 24c does not have a reinforcing member arranged in the hollow portion having a rectangular cross section, and the heated foam material f43 is placed on the indoor side surface of the upper portion of the outdoor side finding wall 24k over the entire width of the outdoor side finding wall 24k. Is placed.

As shown in FIGS. 3 (b) and 4 (a), the vertical stile 24 has a resin end cap 80 arranged at the upper end thereof. The vertical stile 24 is also provided with a resin end cap at the lower end.
The end cap 80 is inserted and fixed in the hollow portion of the vertical stile body 24c, and guides the upper rail to prevent the upper part of the sash 20 from swinging, and the steady rest 81 and the door end side of the steady rest 81. It has a pulling portion 82 which is continuously arranged in the groove portion 24b and abuts on the pulling piece of the right vertical frame 14 to pull the shoji 20 toward the room side.

The steady rest 81 of the end cap 80 has fitting ribs 81a at the left and right ends in the finding direction on the indoor side surface and the outdoor side surface of the portion to be inserted into the vertical stile body 24c, and the left and right fitting ribs 81. It has an upper wall portion 81c that connects the upper end portions of 81a and 81a to each other. In some cases, the left and right fitting ribs and the like may not be provided on the indoor side surface of the steady rest 81 of the end cap 80.
Of the fitting ribs 81a, the fitting ribs 81a and 81a formed at least at the left and right ends of the outdoor side surface in the finding direction have missing portions 81b and 81b formed in the lower portion in the indoor direction.

Then, the end cap 80 in which the steady rest portion 81 is inserted into the hollow portion of the vertical stile body 24c is fixed so as to cover the upper end opening of the hollow portion by the upper wall portion 81c.

The heated foaming material f43 arranged in the hollow portion of the vertical stile body 24c has a lower portion f43a having the same dimensions as the found dimension of the outdoor side finding wall 24k, and relief portions f43c and f43c at both ends in the finding direction. It has an upper portion f43b formed.

When arranging the heated foaming material f43 on the vertical stile 24, the heated foaming material f43 is inserted from the upper opening of the stile body 24c so that the lower portion f43a is on the bottom, and the heated foaming material f43 is inserted into the outdoor side finding wall 24k. It is fixed by a fixing means such as double-sided tape.
After that, the upper portion of the vertical stile 24 is formed by inserting the end cap 80 from the upper opening of the vertical stile body 24c, but the fitting ribs 81a and 81a on the outdoor side of the steady rest portion 81 of the end cap 80 are formed. Since the missing portions 81b and 81b are formed in the space, the fitting ribs 81a and 81a may interfere with the heated foam material f43 fixed to the outdoor side finding wall 24k as shown in FIG. 4 (b). Absent.

As shown in FIGS. 4A and 4B, in the heated foaming material f43 arranged in the hollow portion of the vertical stile 24, the upper portion f43b is near the upper end of the vertical stile 24 and the fitting rib 81a of the end cap 80 is formed. It is arranged between 81a, and the lower portion f43a is arranged over the entire width of the outdoor side finding wall 24k of the vertical frame main body 24c.

The heated foam material f43 is arranged so that the upper end of the lower portion f43a is located above the lower end of the upper rail guided by the steady rest portion 81 of the end cap 80, so that the outdoor side of the upper rail is located. It faces the side surface over the entire length of the hollow portion of the rail 24 in the width direction.
Further, as shown in FIG. 5, the heated foam material f43 is arranged so that the lower end of the lower portion f43a has an insertion hole for the tapping screw b41 for connecting the upper stile 21 of the vertical stile body 24c. There is.

As described above, in the sash of the present embodiment, the heated foam material is arranged over the entire width of the indoor side surface of the outdoor wall (mitsuke wall) at the upper position of the sash in the finding direction. Therefore, in the event of a fire, the sash is hollow. The space can be closed over a wide area of the part.
Then, a missing portion is formed in the fitting rib into which the end cap arranged at the upper end of the vertical stile is inserted, so that the heated foam material provided on the outdoor wall (mitsuke wall) of the vertical stile has an end portion. It can be placed over the entire width in the finding direction up to the range facing the outdoor surface of the cap, and foams in the event of a fire, and the gap between the upper rail and the stile guided by the end cap is over the entire width of the stile. Can be filled.

In addition, the heated foaming material that is arranged over the entire width of the hollow part of the vertical stile is arranged so that the lower end position reaches the insertion hole of the tapping screw for framing, and by foaming in the event of a fire, the vertical Since the tapping screw insertion holes formed in the inner peripheral wall and the outer peripheral wall of the hollow portion of the stile are spread, communication between indoors and outdoors at the upper position of the stile can be reliably suppressed.

In addition, the heated foaming material foams over the entire width of the found wall of the sash and fills the hollow part, which suppresses the transfer of heat to the sash in the event of a fire and suppresses the deformation of the sash due to heat. The reinforcing member may be omitted depending on the dimensions and the like.

The lower end position of the heated foaming material arranged in the upper portion in the hollow portion of the vertical stile is not limited to the position of the insertion hole of the tapping screw.
For example, if some kind of hole such as an air introduction hole is formed in the vicinity below the insertion hole of the tapping screw, the heated foaming material may be arranged up to the position of the hole.
Further, the heated foaming material arranged near the end portion of the vertical stile is not limited to the upper portion of the vertical stile, and may be arranged in the lower portion of the vertical stile.

Although the present embodiment has been described above using the sliding window, the configuration of the sash such as the raising / lowering window and the FIX window is not limited at all.
It goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
