• wherein the molding portion main body is configured to come into contact with a door arrangement portion where at least a part of the door which is closed is configured to be disposed,
• the molding portion further includes a coupling portion for connecting the molding portion main body with the window assembly, and
• when the molding portion main body contacts a part of the door which is closed, the molding portion main body is configured to be flattened while the molding portion main body pivots about a contact point, at which the molding portion main body is in contact with the door arrangement portion no matter when the door is open or closed, in a direction in which the molding portion main body moves away from the window assembly such that an angle formed between the molding portion main body and the coupling portion increases.
