Abstract
An air passage switching system includes a switching door that is disposed rotatably in a case to open and close an air passage of the case. The switching door includes a door body, a rotation shaft provided in the door body, and a seal member made of an elastomer and adhering to an outer peripheral portion of the door body. The seal member contacts on a sealing surface of the case when the switching door closes the air passage. A plurality of recess portions are formed on the outer peripheral portion of the door body to be arranged in an outer peripheral direction. Thus, adhesion between the door body and the seal member can be strengthened.
