PROBLEM TO BE SOLVED: To provide a vehicle outer mirror device capable of reducing aerodynamic noise in a wider vehicle speed range and suppressing reduction in an aerodynamic noise reduction effect caused by the entry of a foreign matter.SOLUTION: A vehicle outer mirror device comprises: an air intake port 24 and an air blowout port 26 formed on an outer cover 14; a communication passage 28 defined in the outer cover 14 and communicating the air intake port 24 and the air blowout port 26 with each other; and a shutter 40 provided to open and close at least one of the air intake port 24 and the air blowout port 26. By closing the air intake port 24 or the air blowout port 26 with the shutter 40, air is prevented from being blown out from the air blowout port 26 to the outside during low-speed travel. Thereby, generation of noise caused by blowing out air is prevented and aerodynamic noise can be suppressed in a wide vehicle speed range. In addition, a foreign matter is prevented from entering the communication passage 28, and thus reduction in an aerodynamic noise reduction effect during middle- and high-speed travel due to an increase of flow passage resistance can be suppressed.SELECTED DRAWING: Figure 5

    【課題】より広い車速域で空力騒音を低減できると共に、異物侵入に起因する空力騒音低減効果の低下を抑制できる車両用アウタミラー装置を提供する。【解決手段】アウタカバー14に形成された空気取入口24及び空気吹出口26と、アウタカバー14内に画成されて空気取入口24と空気吹出口26とを互いに連通する連通路28と、空気取入口24及び空気吹出口26の少なくとも一方を開閉するように設けられたシャッター40とを有する構成とする。空気取入口24又は空気吹出口26がシャッター40により閉じられることにより、低速走行時に空気吹出口26から空気が外部に吹き出ないようになる。これにより、空気の吹き出しによる騒音発生が防止され、幅広い車速域で空力騒音を低減できる。また、異物が連通路28に侵入することが防止され、流路抵抗の増大による中高速走行時の空力騒音低減効果の低下が抑制される。【選択図】図5
