It protrudes toward the outdoor side 11 from the surface of the outdoor side 11. In the second fin portions 55, 55 ..., The end of the indoor side 12 is in contact with the surface of the outdoor side 11 of the combination stile 43 of the internal sash 4, and the end of the outdoor side 11 is the combination stile 32 of the external sash 3. It is in contact with the indoor side 12 surface (see FIG. 1).

図９に示すように、内障子４は、上框４１、下框４２、召合せ框４３、縦框（戸先框）４４とこれらの框４１〜４４の内側に組み込まれた複層ガラス４５と、を有している。
内障子４には、召合せ框４３の室外側の面の上端部近傍に第１振れ止め部材４６が設けられていて、縦框４４の室外側の面の上端部近傍に第２振れ止め部材４７が設けられている。 As shown in FIG. 9, the internal sash 4 includes an upper stile 41, a lower stile 42, a combination stile 43, a vertical stile (door end stile) 44, and a double glazing 45 incorporated inside these stiles 41 to 44. And have.
The inner sash 4 is provided with a first steady rest member 46 near the upper end of the outdoor surface of the mating stile 43, and a second steady rest member near the upper end of the outdoor surface of the vertical stile 44. 47 is provided.

第１振れ止め部材４６は、図５に示すように内障子４が閉鎖状態の場合には、室外側１１の先端部が風止め板５の第１側板部５２の室内側１２の面と当接し、図１０に示すように内障子４が閉鎖状態から見付け方向一方側に移動した場合には、室外側１１の先端部が樹脂カバー６の第１側板部６２の室内側１２の面と当接するように、召合せ框４３からの突出寸法Ｌ１が設定されている。 As shown in FIG. 5, in the first steady rest member 46, when the internal sash 4 is in the closed state, the tip portion of the outdoor side 11 is in contact with the surface of the indoor side 12 of the first side plate portion 52 of the windbreak plate 5. When the sash 4 is in contact with the sash and moves from the closed state to one side in the finding direction as shown in FIG. The protrusion dimension L1 from the combination stile 43 is set so as to be in contact with each other.

第２振れ止め部材４７は、内障子４が閉鎖状態であっても開口状態であっても、図６に示すように常に室内側レール２１３の下端部近傍の室内側１２の面と当接している。第２振れ止め部材４７は、内障子４が開口状態となると、風止め板５の切欠き部５２３（図７）の内側（風止め板５の第２基部５２１Ｂの下側）に配置された状態で中間レール２１４の下部側の室内側１２の面２１４ｂ（図８参照）と当接している。 The second steady rest member 47 is always in contact with the surface of the indoor side 12 near the lower end of the indoor side rail 213 as shown in FIG. 6, regardless of whether the internal sash 4 is in the closed state or the open state. There is. The second steady rest member 47 was arranged inside the notch 523 (FIG. 7) of the windbreak plate 5 (below the second base portion 521B of the windbreak plate 5) when the internal sash 4 was opened. In this state, it is in contact with the surface 214b (see FIG. 8) of the indoor side 12 on the lower side of the intermediate rail 214.

第２振れ止め部材４７は、室外側１１の先端部が中間レール２１４の室内側１２の面と当接するように縦框４４からの突出寸法Ｌ２が設定されている。
風止め板５の第１側板部５２および樹脂カバー６の第１側板部６２の室内側１２の面は、中間レール２１４の室内側１２の面よりも室内側１２に配置されていることにより、第１振れ止め部材４６の召合せ框４３からの突出寸法Ｌ１は、第２振れ止め部材４７の縦框４４からの突出寸法Ｌ２よりも小さくなるように設定されている。 The second steady rest member 47 has a protrusion dimension L2 from the vertical stile 44 set so that the tip end portion of the outdoor side 11 comes into contact with the surface of the indoor side 12 of the intermediate rail 214.

The protrusion dimension L1 of the first steady rest member 46 from the combined stile 43 is set to be smaller than the protrusion dimension L2 of the second steady rest member 47 from the vertical stile 44.

次に、上述したサッシの作用・効果について図面を用いて説明する。
上述した本実施形態によるサッシ１では、樹脂カバー６が中間レール２１４の室内側１２の面と先端部とを覆っていることにより、室外の冷気によって中間レール２１４が冷やされた場合もその冷気が室内側１２に伝達されることが抑制されるため、中間レール２１４の室内側１２に生じる結露を抑制することができる。
また、第１振れ止め部材４６の召合せ框４３の室外側１１の面からの突出寸法Ｌ１は、第２振れ止め部材４７の縦框４４の室外側１１の面からの突出寸法Ｌ２よりも小さくなるように設定されていることにより、内障子４が開閉する際には、第１振れ止め部材４６が樹脂カバー６の第１側板部６２と当接しているとともに、第２振れ止め部材４７が中間レール２１４と当接している状態が維持されるため、中間レール２１４の下端部分が樹脂カバー６に覆われている場合でも、内障子４をスムーズに開閉することができる。 Next, the actions and effects of the above-mentioned sash will be described with reference to the drawings.
In the sash 1 according to the present embodiment described above, since the resin cover 6 covers the indoor side 12 surface and the tip portion of the intermediate rail 214, even if the intermediate rail 214 is cooled by the outdoor cold air, the cold air is released. Since transmission to the indoor side 12 is suppressed, dew condensation generated on the indoor side 12 of the intermediate rail 214 can be suppressed.
Further, the protrusion dimension L1 from the surface of the outdoor side 11 of the combined stile 43 of the first steady rest member 46 is smaller than the protrusion dimension L2 from the surface of the outdoor side 11 of the vertical stile 44 of the second steady rest member 47. When the internal sash 4 is opened and closed, the first steady rest member 46 is in contact with the first side plate portion 62 of the resin cover 6, and the second steady rest member 47 is in contact with the first side plate portion 62. Since the state of contact with the intermediate rail 214 is maintained, the internal shoji 4 can be smoothly opened and closed even when the lower end portion of the intermediate rail 214 is covered with the resin cover 6.

風止め板５の第１側板部５２の室内側１２の面は、樹脂カバー６の第１側板部６２の室内側１２の面と連続するように設けられていることにより、内障子４が開閉移動する際に、第１振れ止め部材４６が樹脂カバー６の第１側板部６２の端部や風止め板５の第１側板部５２の端部に引っ掛かることなくスムーズに移動することができる。 The indoor side 12 surface of the first side plate portion 52 of the windbreak plate 5 is provided so as to be continuous with the indoor side 12 surface of the first side plate portion 62 of the resin cover 6, so that the internal shoji 4 can be opened and closed. When moving, the first steady rest member 46 can move smoothly without being caught by the end of the first side plate 62 of the resin cover 6 or the end of the first side plate 52 of the windbreak plate 5.
