PROBLEM TO BE SOLVED: To provide an intake duct capable of reliably preventing such a phenomenon that rainwater pouring onto the head part upper face of the intake duct is sucked thereinto from an air intake port.SOLUTION: An intake duct 7 for taking in outside air as engine intake air from an air intake port 2 opened to the vehicle-width-direction outside of a head part 4a riding on the upper face of a cab of a vehicle, where the air intake port 2 is opened to avoid the just upper side of a duct part 4b extending downward from the rear part lower face of the head part 4a along the rear face of the cab, includes a vertical wall 10 provided at a position adjacent to the rear end of the air intake port 2 for damming water residing on a bottom face 11 of the head part 4a.SELECTED DRAWING: Figure 1
【課題】吸気ダクトのヘッド部上面に降り注いだ雨水が空気取入口から吸い込まれてしまう現象を確実に防止し得る吸気ダクトを提供する。【解決手段】車両のキャブの上面に乗り上げたヘッド部4aの車幅方向外側に開口した空気取入口2から外気をエンジン用吸気として取り入れる吸気ダクト7に関し、前記ヘッド部4aの後部下面から前記キャブの後面に沿い下方へ延びるダクト部4bの直上を避けて前記空気取入口2を開口し、該空気取入口2の後方端と隣接する位置に前記ヘッド部4aの底面11に溜まる水を堰き止める竪壁10を備えた。【選択図】図1
