Abstract
An inside air/outside air switching case employing a rotary door, since an introduced air flows along an inner surface of a circumferential wall of the rotary door, an air flow guiding portion constructed of a plurality of protruding portions formed in a corrugated shape of concavities and convexities is formed on an inner surface of the circumferential wall of the rotary door. In this way, the air flow directed toward a suction inlet is made uniform by means of the guiding portion, and the air flow noise can be suppressed.
