wherein the recess receives the projection upon a side collision of the vehicle.
2. The vehicle body side structure according to claim 1 , wherein:
the side sill has a side face portion formed into a sheet shape on an outer side of the side sill in the width direction; and
the force transferring member is disposed so as to overlap the side face portion when seen from the side.
3. The vehicle body side structure according to claim 1 , wherein a vertical length of the projection is set shorter than a vertical length of the recess.
4. The vehicle body side structure according to claim 2 , wherein a vertical length of the projection is set shorter than a vertical length of the recess.
5. The vehicle body side structure according to claim 1 , wherein the projection is disposed below the recess.
6. The vehicle body side structure according to claim 2 , wherein the projection is disposed below the recess.
7. The vehicle body side structure according to claim 3 , wherein the projection is disposed below the recess.
8. The vehicle body side structure according to claim 1 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.
9. The vehicle body side structure according to claim 2 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.
10. The vehicle body side structure according to claim 3 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.
11. The vehicle body side structure according to claim 5 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.
12. The vehicle body side structure according to claim 1 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.
13. The vehicle body side structure according to claim 2 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.
14. The vehicle body side structure according to claim 3 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.
