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.

Rear body structure for vehicles

A rear vehicle-body structure of a vehicle can enhance the performance of protecting a vehicle component disposed under a rear floor against a rear-end collision load. The rear vehicle-body structure of a vehicle includes a rear bumper reinforcement having a rear bumper beam extending in a vehicle width direction along a rear bumper and load absorbing parts extending from left and right ends of the rear bumper beam toward a vehicle front side, and rear side frames extending in a vehicle front-rear direction respectively along left and right side portions of a rear floor and coupled at rear ends to front ends of the load absorbing parts, with a vehicle component being disposed under the rear floor. A vertical center of the rear bumper beam is located lower than a respective vertical center of each of the rear side frames.

Rear vehicle-body structure of vehicle

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.
