PROBLEM TO BE SOLVED: To prevent deformation of an intake duct caused by heat.SOLUTION: An intake duct 20 includes a cylindrical duct body 22 which defines an air flow passage 22a for guiding air taken from an air inlet 24 to an engine mounted on a vehicle body, and a pair of attachment parts 28, 28 which is provided on the air inlet 24 side of the duct body 22 and is fixed to the vehicle body by fastening means 16. In the duct body 22, a slit 42 is provided on an installation wall 30 defining the vehicle body side on which the attachment parts 28 are fixed in the air inlet 24 in such a manner that the slit 42 is positioned between the pair of the attachment parts 28, 28.SELECTED DRAWING: Figure 2
