Abstract
In a window structure equipped on the side walls of a cabin in the body of an airplane, a transparent board is mounted on the outer portion for sealing the pressure inside the cabin. A dust cover is mounted in the inner side of the transparent board sealing the pressure, and a shade 80 which is able to take an up and down movement is mounted on the cabin side of the dust cover for blocking outer incident light. The dust cover comprises of a transparent resin board and a non-elastic film stuck on the surface of the transparent resin board facing the shade. The acrylic resin used as the material of the transparent resin board expands by absorbing the water in the air, but by the operation of the non-elastic film, the dust cover bends toward the outer direction F of the body, and will not interfere with the locus L.sub.1 of the up and down movement of the shade.
