To provide an intake duct structure which can discharge a liquid to the outside of a duct when the liquid enters from an intake port while inhibiting pressure loss.SOLUTION: An intake duct structure 10 includes: a duct 15 provided with an intake port 15a for taking air in a passenger compartment; and a rotating body 20 disposed in the duct 15. The rotating body 20 includes: a plate-like member 21 having a first end 21a and a second end 21b; and a support part 22 rotatably supporting the plate-like member 21. The plate-like member 21 is provided so as to be rotatable between a first attitude in which the plate-like member 21 is arranged along an intake direction intersecting with a vertical direction and a second attitude in which the second end 21b is located below the first end 21a and the plate-like member 21 inclines so as to rise gradually toward the downstream side in the intake direction. The duct 15 is provided with: a first rotation restriction part 60 which restricts rotation of the plate-like member 21 so that the first attitude is maintained; and a second rotation restriction part which restricts rotation of the plate-like member 21 so that the second attitude is maintained.SELECTED DRAWING: Figure 2
【課題】圧損を抑制しつつ、吸気口から液体が浸入した場合にダクトの外部に液体を排出可能な吸気ダクト構造を提供する。【解決手段】吸気ダクト構造10は、車室内の空気を吸気するための吸気口15aが設けられたダクト15とダクト15内に配置された回転体20とを備え、回転体20は、第1端部21aおよび第2端部21bを有する板状部材21と板状部材21を回転可能に支持する支持部22とを含み、板状部材21は、上下方向に交差する吸気方向に沿う第1姿勢と、第2端部21bが第1端部21aよりも下方側に位置し、吸気方向の下流側に向かうにつれて上方に向かうように傾斜した第2姿勢との間で回転可能に設けられ、ダクト15には、第1姿勢が維持されるように板状部材21の回転を規制する第1回転規制部60と、第2姿勢が維持されるように板状部材21の回転を規制する第2回転規制部とが設けられている。【選択図】図2
