Claims

[Scope of Claim for Utility Model Registration] (1) An exhaust pipe that discharges the exhaust gas inside the muffler to the outside of the muffler is provided with a ventilator pipe that branches from this exhaust pipe to the bottom side of the muffler, and the water at the bottom of the muffler is removed from the exhaust gas. In the water drainage structure of a vehicle exhaust system, where the negative pressure associated with the flow velocity of the exhaust gas is sucked up by the ventilate pipe and discharged to the outside of the muffler via the exhaust pipe, the exhaust gas is drawn in the middle of the exhaust pipe that leads the exhaust gas to the muffler. A branch pipe is installed in the muffler, and the middle of the branch pipe is installed along the bottom side wall of the muffler, and the end of the pipe is connected to the exhaust pipe that discharges the exhaust gas inside the muffler to the outside of the muffler. A water drainage structure for a vehicle exhaust system, which is characterized by the following: (2) The branch pipe is formed by branching from the middle of the exhaust pipe on the engine side rather than the bent part formed in the middle of the exhaust pipe on the engine side from the muffler.Claim 1 of the Utility Model Registration Claim Water drainage structure for the vehicle exhaust system described.
