Further, the lighting window 20 of the front door 1 has a large vertical dimension, but a small width dimension in the left and right directions. Therefore, even if the second holding fixture is not provided on the upper and lower surfaces of the multilayer glass 21, The fall of the multilayer glass 21 can be prevented. Moreover, since the 1st opposing surface part 613 and the 2nd holding | maintenance metal fitting 62 are not provided in the upper surface and lower surface of the multilayer glass 21, heat insulation performance can be improved.

Further, as the resin frame 40, there may be a resin frame 40 that does not have the heating foam material 47 facing the indoor surface 21B of the plate glass 212, such as the upper frame 40E, the lower frame 40F, and the vertical frames 40G and 40H shown in FIGS. . A part of the heating foam material 45 faces the gap between the indoor surface 21B of the plate glass 212 and the indoor side holding portion 42. Therefore, when the heating foam material 45 is foamed, the gap between the plate glass 212 and the indoor side holding portion 42 is used. Can also be blocked.
Furthermore, as the inner bone 13, as shown in FIGS. 9 and 10, inner bones 13E, 13F, 13G, and 13H that do not include the bracket 150 may be used. In this case, the indoor surface material 15 may be attached to the inner bone 13E with an adhesive or the like.
