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.

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.
