<p>PROBLEM TO BE SOLVED: To suppress ventilation resistance, reduce noise, and improve damper operability in a case of switching an air flow by a damper.SOLUTION: A position of a damper 15 is switched over between a defroster route opening position and a ventilation route opening position. A closing plate 15b is formed to be along an air flow in a defroster route R4 when the damper 15 is at the defroster route opening position, and to be along an air flow in the ventilation route R5 when the damper 15 is at the ventilation route opening position.</p> |
