PROBLEM TO BE SOLVED: To allow proper crushing deformation when an external force is applied, while allowing restoration to an original shape when the external force is released. SOLUTION: An intake duct D for a vehicle has an abutment support member 50 loosely fitted to a through-hole 40 formed to a first duct wall part 22 and extended in a duct body 20 so that a tip thereof is opposed to the inside of a second duct wall part 24. The abutment support member 50 is supported by a plate member 60 disposed to the first duct wall part 22 and elastically deformed so that the attitude of the abutment support member 50 can be fallingly displaced to the inside of the through hole 40. A shutter part 65 is disposed to the plate member 60. The shutter part 65 covers the through-hole 40 when the duct body 20 is not deformed, and opens the through-hole 40 when the attitude of the abutment support member 50 is fallingly displaced.
