To suppress bending of rockers at time of side collision without increasing the number of parts.SOLUTION: A pair of rockers 106 of a vehicle lower unit structure 102 include a first flat unit 130 of a prescribed height and a second flat unit 134 which is lower than the first flat unit. At least one of cross members 108 includes a top surface unit 140 on a higher side than the first flat unit 130 and a bottom surface unit 146 in a position with the same height as the second flat unit 134. A coupling member 114 is provided with an inclined surface 166 inclining upward from an outside joint unit 162 joined to the first flat unit 130 to an inside joint unit 164 joined to the top surface unit 140.SELECTED DRAWING: Figure 1
【課題】部品点数を増加させることなく、側突時のロッカの屈曲を抑制する。【解決手段】車両下部構造102の一対のロッカ106は、所定高さの第一平坦部130と、これより低い第二平坦部134と、を有する。クロス部材108の少なくとも1つは、第一平坦部130よりも上側の上面部140と、第二平坦部134同じ高さ位置の下面部146と、を備える。連結部材114は、第一平坦部130と接合される外側接合部162から、上面部140と接合される内側接合部164へと上向きに傾斜する傾斜面166を備える。【選択図】図1
