To provide a vehicle lower part structure which inhibits occurence of noise by wind in a narrow band while preventing water from accumulating at the upper surface side of an absorber.SOLUTION: A vehicle lower part structure includes: a lower bumper 20; and an absorber 30 disposed at a rear side lower part of the lower bumper 20. The lower bumper 20 has inclined surface parts 24a, 24b which gradually incline rearward from a front part in a downward direction. At an upper surface part 31 of the absorber 30, a cylindrical rib structure comprising a plurality of vertical walls extending upward from an upper surface is provided. Through holes 39 are formed at a bottom part of the rib structure. A projection part 37 protruding downward and extending in a width direction is provided at a lower surface part 33 of the absorber 30. The through holes 39 are disposed at the front side in an intermediate part in the width direction of the projection part 37.SELECTED DRAWING: Figure 8
【課題】アブソーバの上面側の水溜まりを防止しつつ、狭帯域風騒音の発生を抑制する。【解決手段】車両下部構造は、ロアバンパ20と、ロアバンパ20の後方側の下部に配置されるアブソーバ30と、を有し、ロアバンパ20は、前部から下方に向かうに従い後方に傾斜する傾斜面部24a,24bを有し、アブソーバ30の上面部31には、上面から上方に延びる複数の縦壁によって構成される筒状のリブ構造が設けられ、リブ構造の底部には、貫通孔39が形成される。アブソーバ30の下面部33には、下方に突出し、幅方向に延びる突起部37が設けられ、貫通孔39は、突起部37の幅方向中間部における前方側に配置されている。【選択図】図8
