  • Patent number: 9776661
    Abstract: A vehicle lower portion structure includes a suspension member, an inclined portion, and a receiving portion. The suspension member is disposed at a lower portion of a space portion at a vehicle body front side of a vehicle cabin. The inclined portion is provided at a vehicle body structural member that is further toward a vehicle body rear side than a rear portion of the suspension member, and has an inclined surface that, when the suspension member moves toward a vehicle body rear side, guides the suspension member toward a vehicle body lower rear side. The receiving portion has a receiving surface that, when the suspension member moves toward a vehicle body obliquely rear side as seen in plan view, receives the suspension member.
