A resin angle member 75 is attached to the end of the inside X2 side of the new vertical frame 35.

[0058] A support protrusion 353 protruding inward in the left-right direction from the end of the outer side X1 of the hollow portion 352 inside the new vertical frame is provided at the end of the outer side X1 of the hollow portion 352 inside the new vertical frame. The FIX shoji screen 12 is housed between the support protrusion 353 and a support member 354 attached to the angle member 75.

[0059] Next, we will explain the cover material 8 and the structure in which the cover material 8 is attached to the remodeled fitting 1. The cover material 8 comprises an indoor-side cover material main body 81, a hollow portion 82, and an end fixed portion 83.

[0060] The indoor-side covering material body 81 is formed as a single, seamless rectangular plate. The indoor-side covering material body 81 has a width wider than the width of the mullion 5 in the left-right direction across the mullion 5 in the facing direction, and covers the indoor side X2 of the renovated fitting 1 from the entire new frame 3A as the new frame on one side in the facing direction to a part of the new frame 3B as the new frame on the other side. The indoor-side covering material body 81 has a length in the longitudinal direction of the indoor-side covering material body 81 that is the same as the length in the longitudinal direction of the mullion 5.

[0061] A plurality of rib-like opposing portions 811 extending from the indoor-side covering material main body 81 toward the outdoor side X1 are provided at predetermined intervals at the end of the width direction (left direction in Fig. 3) of the indoor-side covering material main body 81. The indoor-side covering material main body 81 is configured so that its length can be adjusted in the direction spanning the one-side new frame 3A and the other-side new frame 3B, which are the left-right directions across the mullion 5 in the outdoor side direction, for example, by being cut along the cut line shown by the two-dot chain line in Fig. 3. The portion of the indoor-side covering material main body 81 to the left of the cut line (the portion to the left of the two-dot chain line on the left in Fig. 3) is removed as an unnecessary portion.

[0062] In this way, the opposing portion 811 at the left end in the width direction of the indoor-side covering material main body 81 from which the unnecessary portion has been removed is positioned opposite the indoor-side covering material opposing portion 76. A wet sealant 84 is filled between the opposing portion 811 and the indoor-side covering material opposing portion 76.

[0063] The hollow portion 82 extends from the center of the indoor-side covering material main body 81 in the left-right direction across the mullion 5 in the facing direction to the end-fixed portion 83. The end-fixed portion 83 has a lower opposing portion 831 formed with a hollow structure and an attached portion 832 that is fixed with screws 155. The attached portion 832 is T-shaped and has multiple screw-fixed portions 833 extending in the facing direction at its midpoint in the indoor-outdoor direction. The screws 155 are threadedly engaged with the screw-fixed portions 833, fixing the attached portion 832 to the angle member 75, thereby fixing the end-fixed portion 83 to the angle member 75. As a result, the covering material 8 is fixed to the new frame 3B via the angle member 75 or the like, and is attached to the renovated fitting 1.

[0064] This allows the indoor side X2 of the mullion 5 to be covered with the covering material 8, preventing the mullion 5 from being exposed and improving the design. This type of configuration can be easily achieved by engaging the indoor side covering material main body 81 to the mullion 5. In particular, because it is fixed to the new frame 3B via angle members 75 or the like, it is possible to increase the degree of freedom in designing the configuration for engaging the indoor side covering material main body 81 to the new frame 3B, thereby improving workability.

[0065] In addition, a single plate-shaped indoor covering material body 81 is engaged with the renovated fixture 1 and positioned so as to cover the area from the new frame 3A on one side to the new frame 3B on the other side that make up the continuous window, including the mullion 5, which makes it easier to install compared to when it is made up of multiple plate-shaped components, and also makes it possible to block heat from the existing frames 2A and 2B.

[0066] Furthermore, since the mounting portion 832 as the fixed portion is fixed to the other side new frame 3B via the angle member 75 with a screw 155, it is possible to make the configuration in which the cover material 8 is less likely to come off the renovated fitting 1 easier to install and improve workability.

[0067] Next, a second embodiment of the present disclosure will be described. In the second embodiment, the configuration of the cover material 8A differs from the configuration of the cover material 8 in the first embodiment.
