Abstract
A fresh air and recirculation air switching case using a rotary door, since an introduced air flows along an inner surface of a circumferential wall of the rotary door, a convex grid is formed on an inner surface of the circumferential wall of the rotary door. In this system, the air flow directed toward a suction inlet is prevented from becoming turbulent behind the rotary door and the air flow noise can be suppressed.
