PURPOSE:To reduce the vibration of an exhauster by causing the basic edge of an exhaust pipe to be fixed to an engine, and then causing a noise eliminator to be supported by a frame by means of a bracket, and then providing a dynamic damper on a part of the exhaust pipe under the engine. CONSTITUTION:In a structure where the basic edge of an exhaust pipe 11, (12) is fixed to an engine 2, and a noise eliminator 13, (14) is supported by a frame 4 by means of a bracket 20, a dynamic damper 30 is provided on the inside of a part of the exhaust pipe located under the engine 2. Thereby, the vibration of an exhauster 10 can be absorbed.
