In order to completely block the air passage in the longitudinal direction when the sliding plug door is fully opened, the retractor 300 should be disposed at a position close to the door carrier 100 when the sliding plug door is closed.

Optionally, the width of the belt 200 is equal to or slightly less than the width of the air duct.

When the sliding plug is opened, the door carrier 100 is first moved in a direction perpendicular to the door panels to open the door panels outwardly, and then the door panels are pulled apart in a direction parallel to the door panels, i.e. during opening and closing of the sliding plug, the moving direction of the door carrier 100 includes a direction perpendicular to the door panels and a direction parallel to the door panels, and for the sake of convenience of description, the moving direction of the door carrier 100 parallel to the door panels is hereinafter referred to as the X direction, and the moving direction of the door carrier 100 perpendicular to the door panels is hereinafter referred to as the Y direction.
