Claims

[Scope of utility model registration request]

An automobile is constructed of a plurality of chambers that function as an expansion chamber or a resonance chamber, and exhaust gas guided through an inlet pipe is muffled by the functions of the plurality of chambers and then discharged to the outside of the vehicle from a tail tube. In the muffler, a pressure valve that can be opened by the pressure of the exhaust gas is installed in a part of the chamber above the highest water level of water stored in the chamber and communicating with the exhaust gas from the inlet pipe. A muffler for a vehicle, characterized in that one opening of a bypass pipe is provided, and the other opening of the bypass pipe is connected to the tail tube at a portion above the highest water level.
