Abstract: A lower vehicle-body structure allows miniaturization of an undercover and prevents an increase in minimum ground clearance. In the lower vehicle-body structure, a vehicle body floor includes step-up portions connected to a floor tunnel on opposite sides of the floor tunnel in a vehicle width direction at least in regions where first and second cross members are disposed on the vehicle body floor. The lower vehicle-body structure includes a mount member that faces the floor tunnel and connects the step-up portions on the opposite sides of the floor tunnel, and includes first and second undercovers that cover a lower side of the mount member so as to be continuous with a bottom surface of the vehicle body floor on outer sides of the step-up portions in the vehicle width direction.

Abstract: A recessed portion is formed at a frame member provided at a rear portion of a vehicle body and having a closed cross section extending in a vehicle longitudinal direction such that a part of a lower face of the frame member is recessed upwardly, where a damper of a rear suspension is inserted and fixed. A front portion of the frame member is joined to a side sill extending in the vehicle longitudinal direction at a position offset outwardly in a vehicle width direction from the frame member. Branch-shaped closed cross sections branching off from the closed cross section inwardly and outwardly relative to the damper are formed at a position corresponding to the recessed portion of the frame member. A portion of the frame member located at the above-described position is wide outwardly.

Abstract: A pair of rear side frames respectively comprise front bending-promotion portions, middle bending-promotion portions and rear bending-promotion portions which cause the rear side frames to bend inward, in a vehicle width direction, in a trough-folding shape in a rear collision of a vehicle, and a longitudinal distance L2 between the front bending-promotion portions and the middle bending-promotion portions is set to be longer than a longitudinal direction L1 between the middle bending-promotion portions and the rear bending-promotion portions. Thereby, there is provided a rear vehicle-body structure of an automotive vehicle which can properly absorb a collision load at a vehicle-body rear portion, even if a rear side frame is made from material which may not cause smooth bucking of the rear side frame.
Abstract translation: 一对后侧框架分别包括前弯曲促进部分，中间弯曲促进部分和后弯曲促进部分，其使后侧框架在车辆宽度方向上向内弯曲，在后方的槽折叠形状 车辆的碰撞以及前部弯曲促进部和中间弯曲促进部之间的纵向距离L2被设定为比中间弯曲促进部和后部弯曲促进部之间的长度方向L1长。 因此，提供了能够适当地吸收车体后部的碰撞载荷的机动车辆的后车身结构，即使后侧框架由不会引起后侧的平滑弯曲的材料制成 帧。
