Abstract: A vehicle body rear part structure for a vehicle includes a side frame, a subframe disposed below the side frame, and a vehicle body frame member disposed on a middle side in the vehicle body front-rear direction with respect to the subframe. The vehicle body frame member includes: a vertical frame offset outwardly in the vehicle width direction with respect to the subframe; and a lateral frame extending inwardly in the vehicle width direction from the vertical frame. A connecting portion is provided on the subframe. The connecting portion includes: an inclined portion extending while being inclined outwardly in the vehicle width direction, to face the vertical frame; and a widening portion widening inwardly in the vehicle width direction up to a position where the connecting portion linearly extends in the vehicle body front-rear direction from the inclined portion, to face the lateral frame.

Abstract: A deck cover is openably provided at a vehicle-body rear portion positioned in back of a cabin. A top portion of a rear wheelhouse is provided at the vehicle-body rear portion. This top portion is configured to be displaced upward, relative to a vehicle-body rear end portion, such as a rear bumper or a rear end panel, by vehicle-body deformation caused by a vehicle rear collision. The deck cover is supported at a position of the vehicle-body rear portion which is located vertically above or in front of the top portion of the rear wheelhouse such that the deck cover is elevated in accordance with upward displacement of the top portion when the vehicle-body rear portion receives a rear-collision load.

Abstract: A rear vehicle-body structure is provided that can absorb a rear-end collision load by a short frame region on a vehicle-body rear side. Embodiments include a rear side frame having a rear-side breaking frame section including a rear-side breakage starting portion on a rear side among breakage starting portions disposed at intervals in a front-rear direction, a front-side breaking frame section including a front-side breakage starting portion on a front side and at which the direction of breakage is opposite from the direction of breakage at the rear-side breakage starting portion, and a middle frame section between the rear-side breakage starting portion and the front-side breakage starting portion. The axial proof stress of the rear-side breaking frame section is lower than the axial proof stress of the front-side breaking frame section; and the middle frame section includes beads at a predetermined interval in an axial direction.

Abstract: 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.

Abstract: A vehicle body rear part structure for a vehicle includes a rear subframe disposed below a rear side frame and extending in a vehicle body front-rear direction. The rear subframe includes a front load absorbing portion and a rear load absorbing portion which extend rearwardly of a vehicle body from an important safety related component disposed on a vehicle body rear part, are disposed on a vehicle body rear side with respect to the important safety related component, and are configured to absorb a collision load when the collision load from rearwardly of the vehicle body is applied. The rear load absorbing portion is disposed on the vehicle body rear side of the front load absorbing portion. Strength of the rear load absorbing portion against compression in an axis direction is set low, as compared with strength of the front load absorbing portion.
