PROBLEM TO BE SOLVED: To provide a double-hung window capable of enhancing heat insulation property and safety in operation.SOLUTION: A double-hung window includes a fixed upper window sash installed in a top part of a frame installed on an opening of a building, and an openable lower window sash 4 installed below the upper window sash. A space 42 is formed between a bottom rail 24 of the lower window sash 4 and a lower frame member 7 of the frame, in which a support part 13a of a support member 13 is disposed that lays a guide groove below the bottom rail 24. A door pull piece 37a protrudes through an opening 42a of the space 42 from a resin bottom rail 37 of the lower window sash 4, and a first fin part 48a is formed on a first soft resin lower frame member 48 of the lower frame member 7, the first fin part extending obliquely downward of the opening 42a. A second fin part 49a that comes in contact with a bottom part of the resin bottom rail 37 of the lower window sash 4 is formed on and extends from a second soft resin lower frame member 49, and two auxiliary fin parts 49b protrudes from a tip of the second fin part 49a in a direction opposite the bottom rail 24. The first soft resin lower frame member 48 and the second soft resin lower frame member 49 are made of a resin softer and more easily deformed than the door pull piece 37a.
【課題】断熱性と操作の安全性を高めることができる。【解決手段】上げ下げ窓１は、建物開口部に設けた枠体内の上部に設けた固定の上障子と下部に設けていて開放可能な下障子４とを備えた。下障子４の下框２４と枠体の下枠７との間に空間４２を形成し、下框２４の下部にガイド溝を走行する支持部材１３の支持部１３ａを設けた。下障子４の樹脂下框３７に空間４２の開口４２ａに突出する引手片３７ａを設け、下枠７の第一軟質樹脂下枠４８に開口４２ａの斜め下方に延びる第一ヒレ部４８ａを形成した。第二軟質樹脂下枠４９には、下障子４の樹脂下框３７の底部に当接する第二ヒレ部４９ａを延ばして形成し、第二ヒレ部４９ａの先端で下框２４と反対側に２本の補助ヒレ部４９ｂを突出させた。第一軟質樹脂下枠４８と第二軟質樹脂下枠４９は引手片３７ａより軟質で変形し易い樹脂である。【選択図】図４
