To effectively block noise generated by an intake pipe or an intake manifold, and to suppress the propagation of noise to a cabin.
The intake air of an internal combustion engine E passes through a first intake pipe 11, a resonator 12, a second intake pipe 13, an air cleaner 14, an air flow tube 15, an intake chamber 18 and a plurality of branch pipes 19A-19D, and is supplied to each cylinder 10. The resonator 12 is disposed at least above one of first branch pipes 19A, 19B disposed at one side of the air flow tube 15, and the air cleaner 14 is disposed at least over one of second branch pipes 19C, 19D disposed at the other side of the air flow tube 15. The resonator 12 and the air cleaner 14 block noise generated by the branch pipes 19A-19D, and suppress the propagation of the noise to the cabin. The air flow tube 15 is disposed between the second intake pipe 13 and the engine body 20, 21, thereby blocking noise generated by the air flow tube 15 the second intake pipe 13, and suppressing the propagation of the noise to the cabin.
