To provide a suction structure for a vehicle suction device, which is able to prevent foreign matter flying not only from a vehicle traveling direction but also from a vehicle width direction from entering a suction inlet and, thereby, is able to improve an engine performance.SOLUTION: A suction duct 30 extends in a vehicle width direction. In one-end part, in a vehicle width direction, of the suction duct 30, a suction inlet 30A for taking in air from inside of an engine room is opening toward a one-end side in the vehicle width direction. The one-end part, in the vehicle width direction of the suction duct 30 is provided with: a first shield wall 71 disposed in the front of the suction inlet 30A; and a second shield wall 72 extending rearward from the other-end part, in the vehicle width direction, of the first shield wall 71 and disposed opposite, in the vehicle width direction, the suction inlet 30A. Using the first shield wall 71 and the second shield wall 72, an air introducing space 70 through which air sucked into the suction inlet 30A passes is defined behind the first shield wall 71 and between the second shield wall 72 and the suction inlet 30A.SELECTED DRAWING: Figure 5

    【課題】車両走行方向だけでなく、車幅方向から飛来する異物に対しても、異物が吸気入口に侵入することを防止でき、エンジン性能を向上させることができる車両用吸気装置の吸気構造を提供すること。【解決手段】吸気ダクト30は車幅方向に延伸し、吸気ダクト30の車幅方向一端部に、エンジンルーム内から空気を取入れる吸気入口30Aが車幅方向一端側を向いて開口している。吸気ダクト30の車幅方向一端部に、吸気入口30Aの前方に配置される第1遮蔽壁71と、第1遮蔽壁71の車幅方向他端部から後方に延び、吸気入口30Aに車幅方向に対向する第2遮蔽壁72と、が設けられ、第1遮蔽壁71および第2遮蔽壁72により、第1遮蔽壁71の後方、かつ、第2遮蔽壁72と吸気入口30Aとの間に、吸気入口30Aに吸気される空気が通過する空気導入空間70が形成される。【選択図】図5
