PROBLEM TO BE SOLVED: To provide a vehicle rear lower part structure that can reduce air resistance while suppressing increase in manufacturing costs.SOLUTION: The vehicle rear lower part structure comprises an exhaust silencer 2 and a rear bumper. The exhaust silencer 2 has a plurality of recessed parts 2b, a plurality of center protruding parts 2c and a plurality of apical protruding parts 2d formed on a lower surface part 2a, a lower side of a vehicle. Each of the plurality of recessed parts 2b is formed so that the lower surface part 2a is recessed into an upper side of the vehicle, and extended in a longitudinal direction of the vehicle. Each of the plurality of center protruding parts 2c and each of the plurality of end protruding parts 2d are formed so that a part of the lower surface part 2a expands toward the lower side of the vehicle, and extend in a vehicle width direction. Between the center protruding parts 2c and between the center protruding parts 2c and the apical protruding parts 2d are interposed the recessed parts 2b.SELECTED DRAWING: Figure 3

    【課題】製造コストの上昇を抑えながら、空気抵抗の低減を図ることができる車両の後方下部構造を提供する。【解決手段】車両の後方下部構造では、排気サイレンサ2とリヤバンパとを備える。排気サイレンサ2は、車両の下方側である下面部2aに、複数条の凹部2bと、複数の中央突起部2cと、複数の端突起部2dと、が形成されている。複数条の凹部2bの各々は、下面部2aが車両の上方側に凹入されてなり、車両の前後方向に延伸する。複数の中央突起部2c及び複数の端突起部2dの各々は、下面部2aの一部が車両の下方側に張出し形成されてなり、車幅方向に延伸する。中央突起部2c同士の間、及び中央突起部2cと端突起部2dとの間には、凹部2bが介在されている。【選択図】図3
