To suppress interference of an intake manifold and a fuel pipe in head-on collision of a vehicle, when an engine is vertically disposed in an engine room.SOLUTION: Vehicle components are disposed at a front side of an intake manifold 10. A fuel pipe is disposed at a rear side of the intake manifold 10. The intake manifold 10 is disposed at an intake downstream end side of a plurality of independent intake pipe portions 11, and has a mounting portion 33 connecting the plurality of independent intake pipe portions 11 respectively to a part at one side in a vehicle width direction of the engine. The mounting portion 33 has a front mounting portion 36 relatively positioned at a front side and a rear mounting portion 37 relatively positioned at a rear side. The rear mounting portion 37 is constituted to have rigidity higher than that of the front mounting portion 36.SELECTED DRAWING: Figure 6 【課題】エンジンをエンジンルームに縦置きする際に、車両前突時に吸気マニホールドと燃料配管とが干渉するのを抑制する。【解決手段】吸気マニホールド１０の前側に車両部品が配置され、吸気マニホールド１０の後側に燃料配管が配置され、吸気マニホールド１０は、複数の独立吸気管部１１の吸気下流端側に設けられ、複数の独立吸気管部１１をエンジンにおける車幅方向の一側の部分にそれぞれ接続する取付部３３を有し、取付部３３は、相対的に前側に位置する前側取付部３６と、相対的に後側に位置する後側取付部３７とを有し、後側取付部３７は、前側取付部３６と比較して剛性が高くなるように構成されている。【選択図】図６
