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 operation and effect of the above-described 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 surface of the intermediate rail 214 on the indoor side 12 and the front end portion, even when the intermediate rail 214 is cooled by the outdoor cold air, the cold air is removed. Since the transmission to the indoor side 12 is suppressed, dew condensation generated on the indoor side 12 of the intermediate rail 214 can be suppressed.
The protrusion L1 of the first steady rest member 46 from the surface of the outdoor side 11 of the mating frame 43 is smaller than the projected length L2 of the vertical stay 44 of the second steady rest member 47 from the surface of the outdoor side 11. When the inner sash 4 is opened and closed, the first steady member 46 is in contact with the first side plate portion 62 of the resin cover 6 and the second steady member 47 is closed. Since the state of contact with the intermediate rail 214 is maintained, even when the lower end portion of the intermediate rail 214 is covered with the resin cover 6, the inner sash 4 can be smoothly opened and closed.

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。 Since the surface of the first side plate portion 52 of the windshield plate 5 on the indoor side 12 is provided so as to be continuous with the surface of the first side plate portion 62 of the resin cover 6 on the indoor side 12, the inner shoji 4 opens and closes. When moving, the first steady member 46 can move smoothly without being caught on the end of the first side plate portion 62 of the resin cover 6 or the end of the first side plate portion 52 of the windshield plate 5.
