PROBLEM TO BE SOLVED: To provide an exhaust system structure having low exhaust resistance while restraining the generation of air flow noise.SOLUTION: In an exhaust system structure of a vehicle, exhaust gas passed through one upstream exhaust path is distributed to two downstream exhaust paths via a branching part 21 connected to the upstream exhaust path, and an opening part 21b communicating with a closed space 11 is provided in a wall surface opposed to the upstream exhaust path side of the branching part 21. A case 4 is provided so as to surround the branching part 21, and the opening part 21b is made to communicate with the closed space 11 formed by the case 4. |
