PROBLEM TO BE SOLVED: To provide an inner and outer air switching device which inhibits the occurence of noise even when air flows thereinto from any of an outer air inflow port and an inner air inflow port.SOLUTION: An inner and outer air switching device 100 includes a case 110 in which an outer air inflow port 111, from which air from an exterior part of a vehicle cabin flows, and an inner air inflow port 112, from which air from an interior part of the vehicle cabin flows, and a guide passage FP for guiding the air flowing from the outer air inflow port 111 or the inner air inflow port 112 to an air conditioning part 400. Distributors 151, 152 for inhibiting noise caused by airflow being bent are disposed in the guide passage FP.SELECTED DRAWING: Figure 4
【課題】外気流入口及び内気流入口のいずれから空気が流入する場合であっても、騒音の発生を抑制することのできる内外気切換装置を提供する。【解決手段】この内外気切換装置100は、車室外からの空気が流入する外気流入口111と、車室内からの空気が流入する内気流入口112と、外気流入口111又は内気流入口112から流入した空気を、空調部400に導くための案内流路FPと、がそれぞれ形成されたケース110を備える。案内流路FPには、空気の流れが屈曲することによって生じる騒音を抑制するための整流板151、152が配置されている。【選択図】図4
