<P>PROBLEM TO BE SOLVED: To provide a switching door, or an opening/closing door for an air path of such as an air conditioning apparatus in which the rigidity of a substrate is maintained, with further reduction in weight promoted. <P>SOLUTION: A door (7) for opening and closing an opening (1a) of an air path is characterized in that the door (7) is provided with: a door body (7a) having a substrate (70) including 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 body (7a) on the opening (1a). 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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
