To inhibit an intake port of an intake duct from being closed with snow.SOLUTION: A vertical duct 11 has: a duct body 22 molded in a cylindrical shape extending in a vertical direction; and an intake port 13 formed at the duct body 22. The vertical duct 11 is disposed at an outer end part as seen in a vehicle width direction at the rear side of a back surface of a cab and fixed to the cab. An intake port cover 12 is a cover which covers the intake port 13 of the vertical duct 11 and defines a cover internal space 17 between a rear surface 22a of the duct body 22 and an outer surface as seen in the vehicle width direction. The cover internal space 17 is continuous with the intake port 13, extends to an inner side in the vehicle width direction at a rear side of the vertical duct 11, and is open to the inner side as seen in the vehicle width direction. An entire area of the intake port 13 of the vertical duct 11 is open to the cover internal space 17. A cover opening 31 is disposed at the inner side relative to the intake port 13 of the vertical duct 11 when viewed in the vehicle width direction.SELECTED DRAWING: Figure 7

    【課題】雪による吸気ダクトの吸気口の閉塞を抑える。【解決手段】バーチカルダクト11は、上下方向に延びる筒状に成形されるダクト本体22と、ダクト本体22に形成される吸気口13とを有し、キャブの背面の後方の車幅方向外端部に配置されてキャブに対して固定される。吸気口カバー12は、バーチカルダクト11の吸気口13を覆うカバーであって、ダクト本体22の後面22a及び車幅方向外側面との間にカバー内空間17を区画する。カバー内空間17は、吸気口13から連続してバーチカルダクト11の後方で車幅方向内側へ延び、車幅方向内側へ開口する。バーチカルダクト11の吸気口13の全域は、カバー内空間17へ開口している。カバー開口31は、バーチカルダクト11の吸気口13よりも車幅方向内側に配置される。【選択図】図7
