To provide a vehicle lower part structure capable of improving the bonding strength between a rocker inner panel and a rocker outer panel.SOLUTION: A vehicle lower structure 10 comprises a rocker inner panel 202, a rocker outer panel 204, and a front pillar inner panel 242. A lower end part 242A of the front pillar inner panel 242 is joined in a state of being sandwiched between an upper flange 202D and an upper flange 204D. The lower end part 242A is provided with an opening 242B penetrating in the thickness direction in a closed cross section 206. A reinforcement member 40 is provided in the closed cross section 206. One end of the reinforcement member 40 is connected to the upper part of the rocker inner panel 202, and the other end of the reinforcement member 40 is connected to the upper part of the rocker outer panel 204 through the opening 242B.SELECTED DRAWING: Figure 1

    【課題】ロッカインナパネルとロッカアウタパネルとの接合強度を向上させることができる車両下部構造を提供する。【解決手段】車両下部構造10は、ロッカインナパネル202と、ロッカアウタパネル204と、フロントピラーインナパネル242とを備える。フロントピラーインナパネル242の下端部242Aが上部フランジ202Dと上部フランジ204Dとの間に挟まれた状態で接合される。下端部242Aには、閉断面206内において厚さ方向へ貫通する開口部242Bが設けられる。閉断面206内には補強部材40が設けられる。補強部材40の一端部はロッカインナパネル202の上部に接合され、補強部材40の他端部は開口部242Bを通してロッカアウタパネル204の上部に接合されている。【選択図】図1
