<p>A door (7) for opening and closing an opening (1a) of an air path, characterized in that the door (7) is provided with: a door body (7a) having a substrate (70) comprising a molded outer frame section (72) and a thin film shaped section (73) inside the outer frame, and a seal section (7c) for the opening section; and a door pivot shaft (7b) for opening and closing the door main body (7a) on the opening section (1a); and in that the thickness (t1) of the thin-film-shaped section (73) in the outer frame is less than the thickness width (T1) between non-level surfaces of the substrate. This configuration makes it possible to maintain the rigidity of the substrate and achieve a further reduction in weight in a switching door or a door for opening or closing an air path for an air conditioning apparatus or the like.</p> |
