Abstract: There are provided a pair of diagonally-extending inclination members which are formed in a substantially X shape in a plan view and provided above or below a floor panel. Each of the pair of inclination members is configured to interconnect a connection portion of one of right-and-left side sills and a hinge pillar and a connection portion of the other of the right-and-left side sills and a center pillar. Thereby, a load-transmission efficiency between a front end of the above-described one of the right-and-left side sills and the other of the right-and-left side sills can be improved in the SOL or vehicle side collisions.
Abstract translation: 在平面图中设置有一对对角延伸的倾斜构件，其形成为大致X形并且设置在地板上方或下方。 所述一对倾斜构件中的每一个构造成将左右两侧梁窗中的一方的连接部与铰链柱和左右两侧梁的另一方的连接部与中柱连接。 因此，在SOL或车辆侧碰撞中，能够提高上述左右侧梁的前端与左右侧梁的另一方的负荷传递效率。

Abstract: A lower vehicle-body structure of a vehicle is provided with a frame member having a closed-cross section. The frame member comprises a first portion and a second portion. The first portion comprises a compression face portion and a pair of side face portions. The side face portion comprises a bending portion, a compression-side area which is positioned on a side of the compression face portion relative to the bending portion and where a compressive stress is generated when the bending load is applied, and a tension-side area which is positioned on a side away from the compression face portion relative to the bending portion and where a tensile stress is generated when the bending load is applied. The compression-side area is configured to have higher rigidity than the tension-side area.

Abstract: A side door comprises a door panel portion and a reinforcement portion (a lower-side reinforcement portion and others). The door panel portion is provided to cover an opening portion for entrance and configured such that its peripheral part overlaps with an opening-portion-forming vehicle-body frame member (a side sill and others) in a vehicle side view. The reinforcement portion is provided at the peripheral part of the door panel portion such that it overlaps with the opening-portion-forming vehicle-body frame member in the vehicle side view, thereby reinforcing the peripheral part of the door panel portion against a collision load applied to the side door from a vehicle side. The reinforcement portion is provided at a portion of the peripheral part of the door panel portion which includes a part corresponding to the vehicle-width-direction-extending vehicle-body frame member (a first floor cross member and others).
