Abstract: A lower vehicle body structure for a vehicle includes a floor panel, a pair of side frames, a battery, a left and right pair of side sills, a cross-member, an impact absorption member, and a reinforcement member. The impact absorption member is disposed at a lower surface side of the floor panel and at a position overlapping the cross-member in a front-rear direction of the vehicle body so as to extend in a vehicle width direction between the side frames and the side sills. Also, the impact absorption member is joined to the side frames and the side sills. The reinforcement member is disposed in the cross-member to extend in the vehicle width direction between portions of the cross-member, which correspond to the left and right pair of side frames in the vehicle width direction.

Abstract: To provide a vehicle-body structure of a vehicle which can achieve both absorption of a front-end collision load acting on a side sill via a front wheel and prevention of receding of the front wheel toward the vehicle-width-direction inner side. The vehicle-body structure of the vehicle 1 includes front wheels 2 and side sills 5 in which a side sill outer 52 and a side sill inner 51 form a closed cross-section; the side sill inner 51 includes an inner body 53 in an open cross-sectional shape open on the vehicle-width-direction outer side, and an inner front end 54 connected to a front end of the inner body 53; the side sill outer 52 includes an outer body 55 in an open cross-sectional shape open on the vehicle-width-direction inner side, and an outer front end 56 connected to a front end of the outer body 55; and the inner body 53, the outer body 55, the inner front end 54, and the outer front end 56 are configured in such a manner that deformation strength against a pressure load from the vehicle front side decreases stepwise in this order.

Abstract: There are provided a side panel constituting a vehicle side face at a higher level than a damper attachment portion suspending a rear wheel, a retractor fixed to a cabin-inside face of the side panel, a frame member forming a closed-cross section extending vertically in corporation with the side panel, and a reinforcing member fixed to the side panel. The reinforcing member comprises a retractor attachment portion to attach the retractor, a gusset portion to partition the closed-cross section of a C pillar reinforcement vertically, and a vibration-damping joint portion joined to the side panel via a vibration-damping material. Herein, the reinforcing member is formed integrally by a member which is configured to be continuous over a range of the retractor attachment portion, the gusset portion and the vibration-damping joint portion.

Abstract: A rear pillar inner provided at a side panel inner and extending upward from a front-side upper portion of a rear wheel house, a rear pillar reinforcement joined to an outside portion of the rear pillar inner, and an outside reinforcing member connecting an outside portion of the side panel inner and the rear wheel house are provided. The rear pillar reinforcement has a rear-side pillar-reinforcement ridge portion extending vertically. The outside reinforcing member has a front-side reinforcing-member ridge portion extending vertically. A lower end portion of the rear pillar reinforcement and an upper end portion of the outside reinforcing member are joined such that the both ridge portions are arranged to align substantially straightly, when viewed from the side, and to slant in such a manner that an upper side thereof is positioned relatively forward compared to a lower side thereof.
