Further, when the base metal fitting 53 is arranged along the notch opening 332a of the resin frame portion 332 of the inner frame 33, the base metal fitting 53 is caught on the resin frame portion 332, so that the base metal fitting 53 can be attached without using a screw. can be placed in the cutout opening 332a. Therefore, the work of arranging the base metal fittings 53 is easy, and since screws for arranging the base metal fittings 53 are not required, the cost required for the screws can be reduced.

また、本実施形態においては、台座金具５３は、縦板５３１の下端部から見込方向に延びる下側横材５３２ｂを更に有し、台座金具５３におけるクレセント部５１側の端部５３ａは、台座金具５３が切り欠き開口３３２ａに沿って配置された場合に切り欠き開口３３２ａの周縁を構成する樹脂框部３３２の表面板３３２ｃの板厚の範囲内に配置される。これにより、台座金具５３を切り欠き開口３３２ａに配置した場合に、台座金具５３は、樹脂框部３３２の表面板３３２ｃの板厚の部分に引っ掛かって、落下することが抑制される。よって、ネジを使用せずに、台座金具５３を切り欠き開口部３３２ａに容易に配置できる。 In addition, in this embodiment, the base metal fitting 53 further has a lower horizontal member 532b extending in the projection direction from the lower end of the vertical plate 531, and the end portion 53a of the base metal fitting 53 on the crescent portion 51 side extends from the base metal fitting. 53 is arranged within the range of the plate thickness of the surface plate 332c of the resin frame portion 332 that constitutes the periphery of the cutout opening 332a when the cutout 332a is arranged along the cutout opening 332a. As a result, when the pedestal metal fitting 53 is arranged in the notch opening 332a, the pedestal metal fitting 53 is prevented from being caught by the thick portion of the surface plate 332c of the resin frame portion 332 and falling. Therefore, the pedestal metal fitting 53 can be easily arranged in the notch opening 332a without using screws.

また、本実施形態においては、台座金具５３の縦板５３１は、切り欠き開口３３２ａにおける室外側に配置される。そのため、火災発生時に、室内側の樹脂框部３３２が全部落下するが、樹脂框部３３２が室内側に落ちるため、縦板５３１が室外側に配置された台座金具５３は落下しない。 Further, in the present embodiment, the vertical plate 531 of the base metal fitting 53 is arranged on the outdoor side of the cutout opening 332a. Therefore, when a fire breaks out, the resin frame portion 332 on the indoor side will all fall, but since the resin frame portion 332 will fall on the indoor side, the pedestal metal fitting 53 with the vertical plate 531 arranged on the outdoor side will not fall.

以上、本発明の好ましい実施形態について説明したが、本発明は、上述の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。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.
