A support surface portion 1d which has a portion 1c and which supports, via beads 100, the viewing surface P1 on the indoor side of the panel P which is fitted from the outdoor side, and supports the viewing surface P2 of the panel P via the setting block 101. It has a support edge 1e. The vertical frame 1a and the horizontal frame 1b are formed to have the same configuration, each having a draining portion 1c, a supporting surface portion 1d, and a supporting edge portion 1e, and both ends are cut off at the corner portion A1 as a cut off structure. They are formed by cutting them diagonally so that they fit together.

As shown in FIG. 3, the vertical ribs 2a and the horizontal ribs 2b are arranged so that the vertical ribs 2a and the horizontal ribs 2a and the horizontal ribs 2a and the fitting protrusions 2c, which are fitted in the fitting recesses 1f formed on the outdoor sides of the vertical frames 1a and the horizontal frames 1b, are fitted. A fin portion 2d is provided on the outer peripheral side of the lining 2b and is provided so as to be in close contact with the viewing surface P3 of the panel P on the outdoor side. As shown in FIGS. 1 and 2, the vertical rim 2a and the horizontal rim 2b are cut obliquely so that both ends meet at the corner portion A1 as a tie-off structure. The fins 2d are made of a resin material that is softer than the vertical rims 2a and the lateral rims 2b, and are elastically deformed when they come into contact with the facing surface P3. Thus, the adhesion to the viewing surface P3 is enhanced.

Deformation can be suppressed. Furthermore, since the cover material 3 is made of aluminum having high heat dissipation, it is possible to suppress the temperature rise of the rim 2 itself due to the heat dissipation, thereby suppressing thermal deformation of the rim 2 . Moreover, the gap S can prevent direct heat transfer and can dissipate the heat of the cover material 3 .

Therefore, the fitting A according to the present embodiment can suppress thermal deformation of the lining 2, which is likely to be thermally deformed by direct sunlight or outside air temperature, while maintaining heat insulation and dew condensation prevention functions. By suppressing the thermal deformation of the rim 2, it is possible to prevent structural defects of the fitting A and maintain a good design for a long period of time.

According to the cover material 3 of the first modified example, the cover material 3 made of aluminum covers the entire viewing surface 20 and the viewing surface 21 of the rim 2 and the middle range of the viewing surface 10 of the frame 1. Therefore, heat can be dissipated in a wider range including not only the viewing surface 20 and the viewing surface 21 of the rim 2 but also a part of the viewing surface 10 of the frame 1.

That is, even if the temperature of the facing surface 10 not covered with the cover material 3 rises, the wide heat dissipation range can suppress the temperature rise of the frame 1 and also prevent heat conduction from the frame 1 to the rim 2. can be suppressed. Therefore, it is possible to expect a higher improvement in heat dissipation, and a higher effect of suppressing the temperature rise of the rim 2 and the frame 1 and suppressing the thermal deformation of the rim 2 and the frame 1 can be expected.
