To provide a lower part vehicle body structure of a vehicle capable of supporting seat rails in a more stable manner.SOLUTION: A lower part vehicle body structure of a vehicle is provided with: a tunnel reinforcement member 5 extending between both end parts as seen in a vehicle width direction of a tunnel part 3A below the tunnel part 3A; seat rail support members 42 provided above a floor part, each having a seat rail attachment part 141 to which a seat rail 6 is attached, and supporting the seat rails 6 from below; and connection members 60, each of which extends in a vertical direction and connects the floor part with the seat rail attachment part 141. The tunnel reinforcement member 5 is connected to a lower surface of the floor part by the connection members 60. The floor part is provided with: fixing parts 131 to which the connection members 60 are respectively fixed. The fixing part 131 has a shape expanding upward from an upper surface of the floor part.SELECTED DRAWING: Figure 5
【課題】シートレールをより安定して支持することのできる車両の下部車体構造を提供する。【解決手段】トンネル部3Aの下方において当該トンネル部3Aの車幅方向の両端部間にわたって延びるトンネル補強部材5と、フロア部の上方に設けられてシートレール5が取付けられるシートレール取付部141を有してシートレール6を下方から支持するシートレール支持部材42と、上下方向に延びて、フロア部とシートレール取付部141とを連結する連結部材60とを設ける。トンネル補強部材5をフロア部の下面に連結部材60によって連結し、フロア部に、連結部材60が固定される固定部131を設け、固定部131をフロア部の上面から上方に膨出する形状にする。【選択図】図5
