[0069] As described above, the existing frame fixing portion 541 of the indoor-side fixing member 54 of the new sill 5 has already been fixed to the first lower plate portion 235 of the existing sill 23. The new frame fixing portion 542 of the indoor-side fixing member 54 of the new sill 5 is brought into contact with the fixing plate portion 513 of the new sill 5 from the indoor side and fixed with screws 96. The existing frame fixing portion 621 of the indoor-side fixing member 62 of the first new vertical frame 6 is brought into contact with the protruding plate portion 244 of the first existing vertical frame 24 from the indoor side and fixed with screws 624, and the new frame fixing portion 622 of the indoor-side fixing member 62 is brought into contact with the indoor plate portion 611 of the first new vertical frame 6 from the indoor side and fixed with screws 625. The second new vertical frame 7 is fixed in the same manner as the first new vertical frame 6.

[0070] Frames 47, 57, and 64 are attached to the indoor side of the new upper frame 4. Frame 47 is installed on the indoor side of the new upper frame 4. The protruding portion 473 of frame 47 is placed above the indoor protruding plate portion 466 of the new upper frame 4. The protruding portion 473 of frame 47 is fixed to the indoor protruding plate portion 466 of the new upper frame 4 with screws or the like. Angle iron 472 is placed at the corner between the indoor side surface 471 of frame 47 and the underside 121 of the window frame 12. The angle iron 472 is fixed to the window frame 12 with screws or the like. Frame 57 is installed on the indoor side of the new sill 5. The protruding portion 573 of frame 57 is placed below the indoor protruding plate portion 566 of the new sill 5. The protruding portion 573 of frame 57 is fixed to the indoor protruding plate portion 566 of the new sill 5 with screws or the like. An angle iron 572 is placed at the corner between the indoor surface 571 of the frame 57 and the top surface 122 of the window frame 12. The angle iron 572 is fixed to the window frame 12 with screws or the like. The frame 64 is installed on the indoor side of the first new vertical frame 6. The protruding portion 643 of the frame 64 is placed on the outside in the width direction of the indoor protruding plate portion 636 of the first new vertical frame 6. The protruding portion 643 of the frame 64 is fixed to the indoor protruding plate portion 646 of the first new vertical frame 6 with screws or the like. An angle iron 642 is placed at the corner between the indoor surface 641 of the frame 64 and the bottom surface 123 of the window frame 12. The angle iron 642 is fixed to the window frame 12 with screws or the like. In this way, the new frame 31 is fixed to the existing frame 21. The shoji screen 32 is fitted into the new frame 31. The fitting 1 of this embodiment is attached to the existing frame 21 using this dry construction method.

[0071] The fitting 1 has a shielding member 8 that is attached to the new frame 31 and shields the gap between the new frame 31 and the existing frame 21. As a result, by attaching the shielding member 8 to the new frame 31, the gap between the new frame 31 and the existing frame 21 can be shielded. Because the position in the indoor / outdoor direction where the fixing part 81 of the shielding member 8 is attached to the new frame 31 can be adjusted, the first fin part 82 connected to the fixing part 81 can be installed in a position where it can shield the gap between the new frame 31 and the existing frame 21. As a result, the gap between the existing frame 21 and the new frame 31 can be covered by the shielding member 8.

[0072] By attaching the shielding member 8 to the new frame 31, construction is easier when installing a new fixture 1 than when attaching the shielding member 8 to the main body 11 or the existing frame 21.

[0073] The shielding member 8 has a fixed portion 81 that is fixed to the new frame 31, and a first fin portion 82 that is connected to the fixed portion 81 and provides shielding between the new frame 31 and the existing frame 21. By adjusting the position of the fixed portion 81 in the indoor / outdoor direction and fixing it to the new frame 31, the gap between the existing frame 21 and the new frame 31 can be covered with the shielding member 8.

[0074] The shielding member 8 has a first fin portion 82 and a second fin portion 84. The first fin portion 82 and the second fin portion 84 are arranged to overlap in the indoor-outdoor direction. This ensures reliable shielding between the existing frame 21 and the new frame 31, and prevents rainwater from seeping in between the existing frame 21 and the new frame 31.

[0075] The fixed portion 81 and the first fin portion 82 of the shielding member 8 are separate members. Therefore, by making it possible to attach first fin portions 82 of different shapes to the same fixed portion 81, it is possible to select an appropriate first fin portion 82 to attach to the fixed portion 81 in order to close the gap between the new frame 31 and the existing frame 21, or the gap between the new frame 31 and the main body 11.

[0076] The shielding member 8 is provided around the entire periphery of the new frame 31. In this way, the gap between the new frame 31 and the existing frame 21 can be blocked around the entire periphery of the new frame 31.

[0077] The first fin portion 82 of the shielding member 8 is formed in an L-shape that fits along the corner of the new frame 31. This makes it possible to close the gap between the new frame 31 and the main body 11 at the corner of the new frame 31. This makes it possible to effectively stop water from leaking from the corner of the new frame 31.

[0078] The first fin portions 82 provided along adjacent corners of the new frame 31 have their ends overlapping in the indoor-outdoor direction. This configuration prevents rainwater from entering from the outdoor side to the indoor side through the gaps between adjacent first fin portions 82.

[0079] Connecting members 85 are attached to the corners of the new frame 31, connecting the fixing portions 481, 581 of the shielding members 48, 58 attached to the horizontal frames with the fixing portions 651, 751 of the shielding members 65, 75 attached to the vertical frames. In this way, the shielding members 8 can be attached to the corners of the new frame 31. This allows for good watertightness at the corners of the new frame 31.

[0080] The present disclosure is not limited to the above-described embodiments and may be modified as appropriate. For example, in the above-described embodiments, the fittings 1, 1B, and 1C may be sashes other than horizontal sliding windows, such as double sliding windows. As in the shielding member 86 of the fitting 1B shown in FIG. 16, the fixing portion 861 and the first fin portion 862 may be integrally formed. For example, the fixing portion 861 may be made of resin, and the fixing portion 861 and the first fin portion 862 may be molded by two-color molding. In such a case, the fixing portion 861 is attached to the new frame 31 so that its position in the indoor / outdoor directions can be adjusted. This facilitates installation and management of the shielding member 8. Since there is no gap between the fixing portion 81 and the first fin portion 82, the thermal insulation of the fitting 1 can be improved.

[0081] The configuration by which the fixing portion 861 of the shielding member 8 is attached to the new frame 31 so that its position in the indoor / outdoor direction can be adjusted may be configured other than a long hole. The shielding member 8 does not have to be attached to the entire periphery of the new frame 31. For example, the shielding member 8 may be attached along the new upper frame 4, the first new vertical frame 6, and the second new vertical frame 7, but not to the new lower frame 5. The shielding member 8 does not have to be provided with the second fin portion 84. It is sufficient that the first fin portion 82 of the shielding member 8 is in contact with either the main body 11 or the existing frame 21. The ends of adjacent first fin portions 82 do not have to overlap in the indoor / outdoor direction.

[0082] The shape of the first fin portion 82 of the shielding member 8 does not have to be L-shaped as described above. For example, the shape of the first fin portion 82 of the shielding member 8 may be linear and extend along the entire length of the vertical or horizontal frame. The position at which the ends of adjacent first fin portions 82 overlap in the indoor / outdoor direction may be set as appropriate. For example, as with fin portions 835 and 836 of the fitting 1C shown in FIG. 17, the first fin portion 82 may be L-shaped and extend along either one or the other widthwise side of the new upper frame 4 and the entire vertical direction of either the first new vertical frame 6 or the second new vertical frame 7. As with fin portion 837 of the fitting 1C shown in FIG. 17, the first fin portion 835b of the fin portion 835 and the end portion 836b of the fin portion 836, which are adjacent in the widthwise direction, overlap in the indoor / outdoor direction. Lower end portions 835c, 836c of fin portions 835, 836 provided along the first new vertical frame 6 and the second new vertical frame 7 extend downward further than the fin portion 837 provided along the new lower frame 5. Both end portions 837b, 837b of the fin portion 837 provided along the new lower frame 5 overlap the lower end portions 835c, 836c of the fin portions 835, 836 provided along the first new vertical frame 6 and the second new vertical frame 7 in the indoor / outdoor direction.

[0083] The shielding member 8 may be attached to the existing frame 21, i.e., the existing upper frame 22, the existing lower frame 23, and a pair of existing vertical frames 24, 25, instead of the new frame 31, to shield the gap between the new frame 31 and the existing frame 21. The shielding member 8 does not have to be configured to have the fixed portion 81, the first fin portion 82, and the second fin portion 84, but may be configured with the fixed portion 81 and the first fin portion 82, or may be configured with only the first fin portion 82. For example, the first fin portion 82 may be configured to be fixed to either the existing frame 21 or the new frame 31. [Explanation of symbols]
