摘要： Interference between an intake manifold and a fuel pipe during a vehicle front collision is prevented in an engine which is longitudinally mounted in an engine room. A vehicle component is arranged on the front side of the intake manifold, and the fuel pipe is arranged on the rear side of the intake manifold. The intake manifold includes a plurality of independent intake pipe portions arranged side by side in the vehicle front-rear direction which branch for each of the cylinders of the engine; and a plurality of coupling portions that each couple adjacent independent intake pipe portions to each other in an integral manner A first coupling portion of the plurality of coupling portions positioned on the frontmost side has a lower rigidity than a third coupling portion of the plurality of coupling portions positioned the rearmost side.
