PROBLEM TO BE SOLVED: To maximally secure the passage cross-sectional area of an intake duct for supplying fresh air to an air cleaner disposed inside an engine room.SOLUTION: An intake duct 19 for introducing fresh air to the inside of a casing 12 of an air cleaner 11, comprises an inlet opening part 19b for sucking fresh air in an engine room, an outlet opening part 19c for supplying the sucked fresh air into the casing 12, and a duct body part 19a connecting the inlet opening part 19b and the outlet opening part 19c. The duct body part 19a is disposed to contact with the surface of the casing 12, so that when the air cleaner 11 and the intake duct 19 are disposed in a narrow space of the engine room, it is possible to prevent a useless space from being formed between the casing 12 of the air cleaner 11 and the intake duct 19 and maximally secure the passage cross-sectional area of the intake duct 19 to enhance the intake efficiency.SELECTED DRAWING: Figure 4

    【課題】 エンジンルームの内部に配置されるエアクリーナに新気を供給するインテークダクトの通路断面積を最大限に確保する。【解決手段】 エアクリーナ11のケーシング12の内部に新気を導くインテークダクト19は、エンジンルームの新気を吸入する入口開口部19bと、吸入した新気をケーシング12内に供給する出口開口部19cと、入口開口部19bおよび出口開口部19cを接続するダクト本体部19aとを備え、ダクト本体部19aはケーシング12の表面に接触するように配置されるので、エンジンルームの狭い空間にエアクリーナ11およびインテークダクト19を配置したときに、エアクリーナ11のケーシング12およびインテークダクト19間に無駄空間が形成されるのを防止し、インテークダクト19の通路断面積を最大限に確保して吸気効率を高めることができる。【選択図】 図4
