To provide a vehicle air intake device capable of: preventing warm air heated in an engine room from flowing to a back side of an air intake port of an air intake duct and being sucked therethrough; and curbing a reduction in engine output due to decreased intake air density.SOLUTION: A radiator 42 with an upper section thereof supported with an upper core support 5 is arranged on a left side of an air intake duct 52 in a vehicle width direction. The air intake duct 52 has a shielding wall section 59, extended to the left side in the vehicle width direction along a rear edge of an upper surface of the upper core support 5, on a left side edge section of an air intake port 53 in the vehicle width direction. The shielding wall section 59 is inclined forward so that a lower edge section thereof is positioned anterior to an upper edge section thereof. The air intake duct 52 has a side wall section 55 extended toward a front side of a vehicle on the left side edge section of the air intake port 53 in the vehicle width direction.SELECTED DRAWING: Figure 2

    【課題】エンジンルーム内で暖められた暖気が吸気ダクトの吸気口に後方から回り込んで吸入されることを抑制でき、吸気密度の低下によるエンジン出力の低下を防止できる車両用吸気装置を提供すること。【解決手段】吸気ダクト52の車両幅方向の左方側に、アッパコアサポート5により上部を支持されるラジエータ42が配置され、吸気ダクト52は、吸気口53の車両幅方向の左方側端部に、アッパコアサポート5の上面の後縁に沿って車両幅方向の左方側に延びる遮断壁部59を有する。遮断壁部59は、その上端部よりも下端部が前方に位置するように、前下がりに傾斜している。吸気ダクト52は、吸気口53の車両幅方向の左方側端部に、車両前方に向かって伸びる側壁部55を有している。【選択図】図2
