A front-side cross member and a rear-side cross member in a front portion of a rear floor are spaced apart from each other, on a top side of the rear floor, ends of the front-side cross member in the vehicle width direction are connected to respective lower ends of left and right brace members extending up and down, while the rear-side cross member is disposed on the rear floor from an underside of the rear floor. A high voltage component is disposed on a top face in the front portion of the rear floor between the front and rear-side cross members, the high voltage component is disposed rearwardly spaced apart from the front-side cross member and closer to the rear-side cross member, and the high voltage component is attached to the front-side cross member via a bracket that deforms under a load in the vehicle front-rear direction.

Rear structure of vehicle

A rear side frame comprises a front-side frame and a rear-side frame which is provided in back of the front-side frame and configured such that a strength thereof against compressing of an axial direction is lower than that of the front-side frame, a rear end portion of the front-side frame and a front end portion of the rear-side frame are overlapped, and another vehicle-body member is connected to an overlap portion where the rear end portion of the front-side frame and the front end portion of the rear-side frame are overlapped.

Reach vehicle-body structure of vehicle

In a rear vehicle-body structure of a vehicle provided with rear side frames, a first deformation promotion portion (recess portions) to promote inward deformation of the rear side frame is provided at each of both-side side face portions of the rear side frame, a second deformation promotion portion (opening portions) to promote outward deformation of the rear side frame is provided at a lower face portion of the rear side frame, and the first deformation promotion portion and the second deformation promotion portion are alternately arranged in an axial direction of the rear side frame.

Rear vehicle-body structure of vehicle

Disclosed is a rear vehicle body structure of a vehicle, which comprises a rear floor panel, and a rear side frame joined to a lower surface of the rear floor panel to extend in a front-rear direction. A bottom wall of the rear side frame has a bottom reinforcing portion formed to protrude upwardly or downwardly, and a standing wall of the rear side frame located on a vehicle-widthwise inner side has a side reinforcing portion formed to protrude outwardly in the vehicle width direction. The bottom reinforcing portion includes a top, an outer inclined section extending from the top obliquely outwardly in the vehicle width direction, and an inner inclined section extending from the top obliquely inwardly in the vehicle width direction, wherein the inner inclined section has an inclination angle less than an inclination angle of the outer inclined section.
