<P>PROBLEM TO BE SOLVED: To provide a highly reliable air duct structure for a construction machine, capable of avoiding a great cost increase of manufacturing the construction machine, and still preventing the breakage of a small-diameter pipe mounted midway in an air duct without worsening its maintainability. <P>SOLUTION: A construction machine includes an air duct for supplying air to an engine mounted on the construction machine, and a small-diameter pipe 48 provided midway in the air duct and adapted to be connected to an external. The air duct has a small-diameter pipe mounting part 34c for the small-diameter pipe to be installed in the air duct. The small-diameter pipe is provided on the small-diameter pipe mounting part, and a guide 52 is formed on the small-diameter pipe mounting part to encircle the small-diameter pipe. <P>COPYRIGHT: (C)2012,JPO&INPIT |
