To provide a vehicle intake device which has a simple and compact structure in which an air intake duct is applicable to a small vehicle, can prevent water from entering an engine in the time of driving through flooded roads by the vehicle and can supply the low-temperature air to the engine in the time of regular driving by the vehicle.SOLUTION: A vehicle-side air intake duct 31 has an air discharge port 31B that opens toward the vehicle rear side and has a rectangular cross-section. An engine-side air intake duct 41 includes an air intake port 42A that opens toward one side of a vehicle width direction and an upstream side passage section 42 that extends from the air intake port 42A toward the other side of the vehicle width direction. When the air discharge port 31B is viewed from the front side of a vehicle, the air intake port 42A and the upstream side passage section 42 are arranged on the inner side of the air discharge port 31B, and a lateral space S2 on the lateral side of the air intake port 42A, and an upper space S1 on the upper side of the upstream side passage section 42 are formed. The vehicle-side air intake duct 31 has a protruding wall section 31G that protrudes to the minute height lower side from its ceiling wall 31C.SELECTED DRAWING: Figure 3

    【課題】吸気ダクトを小型車両に適用可能な簡素で小型な構造としつつ、車両の冠水路走行時にエンジンへの水の侵入を防止でき、車両の通常走行時に低温の空気をエンジンに供給できる車両用吸気装置を提供すること。【解決手段】車体側吸気ダクト31は、車両後方を向いて開口し、かつ、その断面が四角形に形成される空気排出口31Bを有する。エンジン側吸気ダクト41は、車両幅方向の一方を向いて開口する空気取入口42Aと、空気取入口42Aから車両幅方向の他方に延びる上流側通路部42と、を有する。空気排出口31Bを車両正面側から見た場合、空気取入口42Aおよび上流側通路部42は空気排出口31Bの内側に配置され、かつ、空気取入口42Aの側方の側方空間S2および上流側通路部42の上方の上方空間S1が形成されている。車体側吸気ダクト31は、その天井壁31Cから微小高さ下方に突出する突出壁部31Gを有する。【選択図】図3
