To provide a quarter vent duct which can improve exhaust performance by boosting wind pressure for bringing an opening into an open state by the oscillation of a butterfly to a vehicle upper side.SOLUTION: A quarter vent duct 10 comprises: a duct main body 16 having an opening 22 for making the inside and outside of a vehicle communicate with each other; a butterfly 18 attached to the duct main body 16 in a state of being inclined to a vehicle vertical direction, and covering the opening 22 from the outside of the vehicle so as to be openable and closable; and lateral ribs 48 whose opening width directions are set as longitudinal directions, which are bridged to the opening width directions of the duct main body 16 at the inside of the vehicle, and whose short directions are inclined to the vehicle vertical direction so that an angle formed of a direction in which the butterfly 18 is supported from the inside of the vehicle, and a direction inclined to the vehicle vertical direction of the butterfly 18 becomes substantially a right angle in a vertical cross section view when viewing it from the opening width directions in a state that the opening 22 is closed by the butterfly 18.SELECTED DRAWING: Figure 3
【課題】バタフライが車両上方側に揺動し開口を開放状態にするための風圧力を増加させることにより、排気性能を向上させることができるクオータベントダクトを提供する。【解決手段】クオータベントダクト10は、車両内側と車両外側とを連通する開口22を備えたダクト本体16と、ダクト本体16に車両上下方向に対して傾斜した状態で取り付けられ、開口22を車両外側から開閉可能に覆うバタフライ18と、開口幅方向を長手方向とし、ダクト本体16の車両内側において開口幅方向に架け渡され、バタフライ18により開口22が閉じられた状態において、バタフライ18を車両内側から支持する方向とバタフライ18の車両上下方向に対する傾斜方向とのなす角度が開口幅方向から見た縦断面視で略直角となるように短手方向が車両上下方向に対して傾斜された横リブ48と、を備える。【選択図】図3
