A window molding includes a main body and a lip part. The body includes an upper surface configured to be affixed to an inner surface of a window and the body is configured to be arranged between the inner surface and a bottom surface part of a frame. The lip part is provided on a portion of the body located on the peripheral wall part side of the frame. In an assembled state, at least a portion of the lip part extends to be closer to the bottom surface part as approaching from the body side to the peripheral wall part side, and a distance from the upper surface to the bottom surface part is defined as L. When the molding is in an unloaded state, the lip part has a portion in which the distance from the upper surface is longer than L.
