To reduce exterior noise by dampening engine noise propagating backward from an engine.SOLUTION: A vehicle 10 to which a vehicular noise reduction structure is applied includes: an engine 13 installed on a vehicle body 11; a suspension member 14 installed on the vehicle body 11 more downward than the engine 13; and a cover 16 with a cover body 17 covering, from downward, a part of an undersurface 12 of the vehicle body 11 more backward than a front end part of the suspension member 14. The cover 16 includes a vertical wall part 24 extending in the vehicle width direction of a crossing direction to the cross direction of the vehicle 10 in such a state as to project upward from a bottom 18 of the cover body 17.SELECTED DRAWING: Figure 3

    【課題】エンジンから後方へ伝播するエンジン音を減衰して車外騒音を低減する。【解決手段】車外騒音低減構造が適用される車両10は、車体11に搭載されたエンジン13と、エンジン13よりも下方で車体11に取付けられたサスペンションメンバ14と、サスペンションメンバ14の前端部よりも後方で車体11の下面12の一部を下方から覆うカバー本体17を有するカバー16とを備える。カバー16は、カバー本体17の底部18から上方へ突出した状態で、車両10の前後方向に対し交差する方向のうち、車幅方向へ延びる縦壁部24を備える。【選択図】図3
