As shown in FIG. 9, the angle portion 510 provided in the upper resin cover 500 of the modified example includes a front side piece 510a extending toward the room in the prospective direction on the lower side, a back piece 510b extending toward the room in the prospective direction on the upper side, and a support piece. It includes a fitting portion 510d.

裏側片５１０ｂが表側片５１０ａよりも長く形成されている。また、裏側片５１０ｂの端部には表側片５１０ａに向かって折り返すように屈曲する屈曲部５１０ｃが形成される。本実施形態の屈曲部５１０ｃは、その先端が下方を向いており、略直角に折れ曲がっている。屈曲部５１０ｃの室内側にはスペース５１７が形成される。また、表側片５１０ａの端部には裏側片５１０ｂに向かって折り返すように屈曲する屈曲部５１０ｅが形成される。屈曲部５１０ｅも略直角に折れ曲がっている。表側片５１０ａと裏側片５１０ｂの間に額縁５の室外側端部５１が挿入される挿入口５１６が形成される。本変形例では、額縁５が挿入された状態で、屈曲部５１０ｃ及び屈曲部５１０ｅのそれぞれの先端面が額縁５に当接する。 The back side piece 510b is formed longer than the front side piece 510a. Further, a bent portion 510c that bends toward the front side piece 510a is formed at the end of the back side piece 510b. The bent portion 510c of the present embodiment has its tip facing downward and is bent at a substantially right angle. A space 517 is formed on the indoor side of the bent portion 510c. Further, a bent portion 510e that bends toward the back side piece 510b is formed at the end of the front side piece 510a. The bent portion 510e is also bent at a substantially right angle. An insertion port 516 into which the outdoor end portion 51 of the frame 5 is inserted is formed between the front side piece 510a and the back side piece 510b. In this modification, with the frame 5 inserted, the tip surfaces of the bent portion 510c and the bent portion 510e come into contact with the frame 5.

支持片嵌合部５１０ｄは、金属製支持部６１５によって支持される部位である。変形例の金属製支持部６１５は、アングル部５１０の支持片嵌合部５１０ｄに嵌合する嵌合部６１５ａと、嵌合部６１５ａからアングル部５１０の裏側片５１０ｂ（下側）に向って延びる延出片６１５ｂと、延出片６１５ｂとは反対側の躯体側に延びる接触片６１５ｃと、を備える。延出片６１５ｂと裏側片５１０ｂの間には弾性部材１１６が配置される。なお、この弾性部材１１６を省略してもよい。 The support piece fitting portion 510d is a portion supported by the metal support portion 615. The metal support portion 615 of the modified example extends from the fitting portion 615a to be fitted to the support piece fitting portion 510d of the angle portion 510 and the back side piece 510b (lower side) of the angle portion 510 from the fitting portion 615a. The extension piece 615b and the contact piece 615c extending to the skeleton side opposite to the extension piece 615b are provided. An elastic member 116 is arranged between the extension piece 615b and the back side piece 510b. The elastic member 116 may be omitted.

以上説明した変形例においても、屈曲部５１０ｃの室内側に形成されるスペース５１７を利用して額縁５の挿入作業をスムーズに行うことができる。また、樹脂製のアングル部５１０によって断熱性を向上させるとともに金属製支持部６１５によってアングル部５１０の支持構造も強固に構成することができる。即ち、上記実施形態と同様の効果を奏することができるのである。 Also in the modified example described above, the frame 5 can be smoothly inserted by utilizing the space 517 formed on the indoor side of the bent portion 510c. Further, the resin angle portion 510 can improve the heat insulating property, and the metal support portion 615 can firmly form the support structure of the angle portion 510. That is, the same effect as that of the above embodiment can be obtained.

上記実施形態及び変形例では、何れもアングル部（内装材保持部）の裏側片が表側片よりも長くなるように構成された例を説明したがこの構成に限定されない。例えば、表側片が、裏側片よりも見込方向室内側に長く、かつ、屈曲部を有する片である構成とすることもできる。 In the above-described embodiment and modified example, an example in which the back side piece of the angle portion (interior material holding portion) is configured to be longer than the front side piece has been described, but the present invention is not limited to this configuration. For example, the front side piece may be longer than the back side piece on the indoor side in the prospective direction and may have a bent portion.

上記実施形態及び変形例では、アングル部の裏側片に屈曲部が形成されているが、屈曲部の端部を室内側又は室外側へ略直角に屈曲させたり、屈曲部を省略したり、表側片と裏側片の長さを同じ長さにしたりすることもできる。 In the above embodiment and the modified example, the bent portion is formed on the back side piece of the angle portion, but the end portion of the bent portion is bent at a substantially right angle to the indoor side or the outdoor side, the bent portion is omitted, or the front side. It is also possible to make the length of the piece and the back side piece the same.
