Inside the outdoor side portion 121, the hollow portion 12a and the hollow portion 12b are arranged in the left-right direction from the wall 4 side to the door body 20 side. On the other hand, inside the indoor side portion 122, the hollow portion 12c, the hollow portion 12d, and the hollow portion 12e are lined up in the expected direction from the outdoor side to the indoor side. The hollow portion 12c is adjacent to the hollow portion 12b of the outdoor side portion 121 in the prospective direction. Therefore, in the entire hanging base side vertical frame 12, the hollow portion 12b, the hollow portion 12c, the hollow portion 12d, and the hollow portion 12e are arranged in the order of the outdoor side to the indoor side in the prospective direction, and are divided into four spaces.

中空部１２ａには、吊元側縦枠１２の長手方向に沿って延びる補強芯材１２３が配置される。補強芯材１２３は、その断面形状が略コ字状に形成されており、コの字の開口側が戸体２０側を向くように中空部１２ａに配置される。即ち、補強芯材１２３は、中空部１２ａ内で壁４側に位置するとともに蝶番６側を向く面を有する第１片１２３ａと、中空部１２ａ内で見込方向屋内側に位置する第２片１２３ｂと、中空部１２ａ内で見込方向屋外側に位置する第３片１２３ｃと、を有する。 In the hollow portion 12a, a reinforcing core member 123 extending along the longitudinal direction of the hanging base side vertical frame 12 is arranged. The reinforcing core member 123 is formed in a substantially U-shape in cross section, and is arranged in the hollow portion 12a so that the opening side of the U-shape faces the door body 20 side. That is, the reinforcing core member 123 has a first piece 123a located on the wall 4 side in the hollow portion 12a and having a surface facing the hinge 6 side, and a second piece 123b located on the indoor side in the prospective direction in the hollow portion 12a.

補強芯材１５１は、吊元側縦枠１２の長手方向に沿って延びるように形成される。補強芯材１５１は、その断面形状が略コ字状に形成されており、コの字の開口側が屋外側を向くように中空部１２ｂに配置される。即ち、補強芯材１５１は、中空部１２ｂ内で戸体２０（後述の蝶番６の枠側羽根部６１）側に位置する戸体側片１５１ａと、中空部１２ｂ内で壁４側に位置する壁側片１５１ｂと、中空部１２ｂ内で見込方向屋内側に位置する屋内側片１５１ｃと、を有する。 The reinforcing core member 151 is formed so as to extend along the longitudinal direction of the hanging base side vertical frame 12. The reinforcing core material 151 is formed in a substantially U-shaped cross section, and is arranged in the hollow portion 12b so that the opening side of the U-shape faces the outdoor side. That is, the reinforcing core member 151 includes a door body side piece 151a located on the door body 20 (frame side blade portion 61 of the hinge 6 described later) side in the hollow portion 12b and a wall located on the wall 4 side in the hollow portion 12b. It has a side piece 151b and an indoor side piece 151c located on the indoor side in the prospective direction in the hollow portion 12b.

Ｌ字裏板１５２は、補強芯材１５１の壁側片１５１ｂの先端に配置される。Ｌ字裏板１５２は、一方の片が壁側片１５１ｂの壁側面に対向するとともに、もう一方の片が見込方向で屋外側を向くように配置される。そして、見込方向で屋外側を向く片は、後述するカバーネジ９５が締結される部分として機能する。 The L-shaped back plate 152 is arranged at the tip of the wall side piece 151b of the reinforcing core material 151. The L-shaped back plate 152 is arranged so that one piece faces the wall side surface of the wall side piece 151b and the other piece faces the outdoor side in the prospective direction.
