An attachment upper frame 41, an attachment lower frame 42, and a pair of attachment vertical frames 43 are assembled and fixed to each other by screws 44 at any two frame assembly portions. According to this, the attachment frame 4 can be firmly fixed by the screws 44 at the portions where the attachment upper frame 41 , the attachment lower frame 42 and the pair of attachment vertical frames 43 are assembled with each other. Therefore, the attachment frame 4 can be firmly and stably attached to the four outer circumferences of the new frame 2 including the exhaust function part 3 .

以上、本開示の好ましい一実施形態について説明したが、本開示は、上述した実施形態に制限されるものではなく、適宜変更が可能である。例えば、アタッチメント枠４は、アタッチメント上枠４１及びアタッチメント下枠４２の長手方向の端部が、アタッチメント縦枠４３の長手方向の端部の上側及び下側を覆うように、アタッチメント上枠４１及びアタッチメント下枠４２の長手方向の端部が配置される、いわゆる横勝ち構造により構成されてもよい。 A preferred embodiment of the present disclosure has been described above, but the present disclosure is not limited to the above-described embodiment, and can be modified as appropriate. For example, the attachment frame 4 is configured such that the longitudinal ends of the attachment upper frame 41 and the attachment lower frame 42 cover the upper and lower sides of the longitudinal ends of the attachment vertical frame 43 . It may be configured with a so-called horizontal structure in which the ends of the lower frame 42 in the longitudinal direction are arranged.

排気機能部３は、新設上枠２１とアタッチメント上枠４１との間、あるいは新設縦枠２３とアタッチメント縦枠４３との間に取り付けられてもよい。 The exhaust function part 3 may be attached between the newly installed upper frame 21 and the attachment upper frame 41 or between the newly installed vertical frame 23 and the attachment vertical frame 43 .

前記実施形態においては、改装建具１を引違い窓タイプの改装サッシに適用した場合について説明したが、これに限定されない。改装建具を、例えば、回転軸を中心に戸体が回転して開閉する開閉式の改装建具や、縦辷り出し式の改装建具に適用してもよい。また、改装建具を、例えば、枠に対して開閉しないで固定して取り付けられるＦＩＸ式の改装建具に適用してもよい。 In the above-described embodiment, a case where the remodeling fitting 1 is applied to a double sliding window type remodeling sash has been described, but the present invention is not limited to this. The refurbishment fittings may be applied to, for example, an opening/closing type refurbishment fittings that opens and closes by rotating a door body about a rotation axis, or a vertically protruding refurbishment fittings. Further, the refurbishment fittings may be applied to, for example, FIX-type refurbishment fittings that are fixedly attached to the frame without being opened or closed.
