PROBLEM TO BE SOLVED: To provide a vehicle capable of appropriately suppressing noise derived from a cooling fan from leaking into a cabin through an intake duct while suppressing a usage amount of a sound absorption member.SOLUTION: A vehicle comprises: an in-vehicle battery; a cooling fan 30 blowing air AR taken in from within a cabin toward the in-vehicle battery; and an intake duct disposed upstream of the cooling fan 30, opening toward the cabin, and constituting a flow passage of the air AR. The intake duct has therein sound absorption members 47 and 48 each formed from a porous sound absorption material for absorbing noise generated by the cooling fan 30. The sound absorption members are fixed to an inner wall 41n in such a way that back spaces 57 and 58 are provided between the inner wall 41n of the intake duct and the sound absorption members.SELECTED DRAWING: Figure 6
【課題】吸音部材の使用量を抑えつつ、冷却ファンにより生じる騒音が吸気ダクトを通じて車室内に漏れ出るのを適切に抑制できる車両を提供する。【解決手段】車両は、車載電池と、車室内から取り入れた空気ARを車載電池に向けて送風する冷却ファン30と、冷却ファン30の上流側に配置され、車室に向かって開口し、空気ARの流路を構成する吸気ダクトとを備える。そして、吸気ダクトは、その内部に、冷却ファン30により生じる騒音を吸音する多孔質の吸音材からなる吸音部材47,48を有する。吸音部材は、吸気ダクトの内壁41nとの間に背後空間57,58を設ける形態で内壁41nに固定される。【選択図】図6
