する問題があることが分かった。Therefore, the present inventor has found that
It has been proposed to provide a cover on the interior frame as shown in the conventional example of Japanese Patent No. 3 to improve the appearance. Above all, the cover is a low heat conductive material such as synthetic resin or synthetic rubber which is easily available in terms of resources. As a result of trial manufacture, it was found that there is a problem that needs further improvement.

に特に下側横枠材の温度差が大きい。More specifically, the synthetic resin cover is attached so as to cover at least the surface of the upper, lower, left, and right sides of the interior frame that faces the sash opening of the lower horizontal frame member. Is larger than the coefficient of thermal expansion of the metallic material forming the. Moreover, the temperature difference when using the heat insulating sash is large. For example, the temperature of the lower horizontal frame material of the outdoor frame is about 80 ° C. under the direct sunlight around the daytime in the Tokyo area in the summer (about the left and right sides and the upper side of the outdoor frame under the same use condition). The temperature of the frame material is about 50 ° C, and the temperature of each frame material on the top, bottom, left and right of the indoor frame is about 25 ° C. Is about −5 ° C. to 0 ° C., and the temperature of each frame member on the upper, lower, left and right sides of the indoor frame is 15 ° C. to 20 ° C. As can be seen from this example, the temperature difference of the lower horizontal frame member is particularly large.

い。Since the cover is partially fixed and at least one end is a free end, the position of the free end is displaced in the longitudinal direction according to the temperature change. As a result, even if the cover extends to the maximum extent, the dimension thereof is longer than the length of the portion of the lower lateral frame facing the fitting frame opening, and there is no difficulty in attaching the cover to the lower lateral frame. At the same time, unlike the case where at least both ends of the cover are fixed, by fixing only a part of the cover, the cover can be contracted after assembling the fitting frame, and moreover, the expansion and contraction of the cover as described above can be prevented. At this time, a load is not significantly applied to the fixed portion of the cover.
