A vertical wall portion is provided at an outer side of the rear middle floor panel in the vehicle width direction. The rear side floor panel is joined to an outer side of the vertical wall portion in the vehicle width direction and includes a weakened portion.

First claim

What is claimed is:

1. A vehicle body side portion structure comprising:
a side sill disposed at a side portion of a vehicle body and extending in a front-rear direction of the vehicle body;
a rear side floor panel that is joined to a rear portion of a floor panel of the vehicle body and extends towards a rear of the vehicle body, and that extends in a vehicle width direction and is joined to the side sill; and
a rear middle floor panel that is provided at an inner side of the rear side floor panel in the vehicle width direction and that covers an energy storage,
wherein the rear middle floor panel includes a vertical wall portion provided at an outer side thereof in the vehicle width direction, and
wherein the rear side floor panel includes a weakened portion and is joined to an outer side of the vertical wall portion in the vehicle width direction.

2. The vehicle body side portion structure according to claim 1 , further comprising a rear side frame extending in the front-rear direction of the vehicle body and disposed under the rear side floor panel, and
wherein part of the rear side frame is connected to the vertical wall portion.

3. The vehicle body side portion structure according to claim 2 , wherein the rear side frame includes a bottom portion and a side portion that rises upward from the bottom portion, and
wherein a lower portion of the vertical wall portion is joined to an outer side of the side portion in the vehicle width direction.

4. The vehicle body side portion structure according to claim 1 , further comprising a rear panel joined to a rear-portion of the rear side floor panel, and extending so as to be inclined upward towards the rear of the vehicle body, and
wherein the rear panel includes a panel bead portion that extends in the front-rear direction of the vehicle body.

5. The vehicle body side portion structure according to claim 1 , wherein the weakened portion is a bead portion of the rear side floor panel that extends in at least one of the front-rear direction of the vehicle body and an up-down direction of the vehicle body.

6. The vehicle body side portion structure according to claim 1 , further comprising a bulkhead member extending in an up-down direction of the vehicle body and joined to a surface of the side sill that is opposite to a surface of the side sill to which the rear side floor panel is joined, and
wherein the rear side floor panel and the bulkhead member are disposed so as to oppose each other in the vehicle width direction.

7. The vehicle body side portion structure according to claim 1 , wherein the rear side floor panel is joined to the side sill at an outer end thereof in the vehicle width direction and is joined to the outer side of the vertical wall portion at an inner end thereof in the vehicle width direction, and the rear side floor panel includes the weakened portion in a body portion thereof between the outer-end and the inner end.

8. The vehicle body side portion structure according to claim 2 , wherein the rear side frame has a substantially U shape comprising a bottom portion and two side portions that rise upward from the bottom portion, and
wherein a lower portion of the vertical wall portion is joined to an outer side surface of one of the two side portions in the vehicle width direction.

9. The vehicle body side portion structure according to claim 8 , wherein the vertical wall portion extends upward from an upper end of the one of the two side portions.
