PURPOSE:To reduce the exhaust vibration noise produced outside by holding the upper and lower parts of a tube housing by an engine holder and a driving shaft housing, keeping elastic bodies, and tightening the upper edge of the tube housing on the engine holder, in floated state by an elastic mount. CONSTITUTION:An exhaust tube 6 is connected with an engine holder 1, and a tube housing 7 is arranged on the periphery of the exhaust tube 6. The tube housing 7 is held on an engine holder 1 and a drive shaft housing 3, holding elastic bodies 8 in the upper and lower parts. The upper edge of the tube housing 7 is tightened on the engine holder 1 by a bolt 10 through an elastic mount 9, and the tube housing 7 is floated. Accordingly, the vibration noise of the exhaust which is transmitted to the engine holder 1 and the drive shaft housing 3 is reduced, and the vibration noise produced from the engine holder 1 and the drive shaft housing 3 can be reduced. |
