PROBLEM TO BE SOLVED: To prevent a heat shrinkage tube from being interfered with another member while suppressing a radiating sound from an intake tube of an engine by the heat shrinkage tube. SOLUTION: A soundproof heat shrinkage tube 34 which covers an outer periphery of the intake tube 18 for introducing intake air into the engine is divided into a first part 34a and a second part 34b, and an upstream side and a downstream side of a part of the intake tube 18 approaching an air cleaner 13 are respectively covered with the first part 34a and the second part 34b. Thus, the intake tube 18 is constituted so that the heat shrinkage tube 34 may not exist in the part approaching the air cleaner 13 while assuring a soundproof effect by interrupting the radiating sound from the intake tube 18. In this manner, the heat shrinkage tube 34 can be prevented from being interfered with the air cleaner 13. As a result, the degree of freedoms of layout of the intake tube 18 and the air cleaner 13 in a narrow engine room 29 can be raised. COPYRIGHT: (C)2005,JPO&NCIPI
