9. A front vehicle body structure comprising:

a front side frame disposed at a front of a vehicle body on each side of a power unit in a vehicle body width direction, the front side frame extending substantially in a fore-and-aft direction of the vehicle body; and

a load transfer member disposed outside the front side frame in the vehicle body width direction, near a front end of the front side frame, a rear end of the load transfer member being fixed to an outer lateral side of the front side frame in the vehicle body width direction at a fixed position, the fixed position being located forwardly of a center position of the power unit in the fore-and-aft direction, a front end of the load transfer member being disposed forwardly of the rear end of the load transfer member in the fore-and-aft direction and outwardly of the rear end of the load transfer member in the vehicle body width direction, wherein

the front vehicle body structure is configured such that, upon input of a predetermined impact load to the front end of the load transfer member in a rearward direction of the vehicle body, a displacing region of the front side frame located at or rearward of the fixed position will be displaced toward a lateral side of the power unit, and

the front side frame has a low-stiffness portion rearward of the fixed position, the low-stiffness portion being configured to promote a bending of the front side frame thereabout.

10. The front vehicle body structure according to claim 9 , wherein the front vehicle body structure is configured such that, upon input of a predetermined impact load to the front end of the load transfer member in a rearward direction of the vehicle body, the displacing region of the front side frame will push against the lateral side of the power unit to push the power unit toward the opposite front side frame.

11. The front vehicle body structure according to claim 9 , wherein the front vehicle body structure is configured such that, upon input of a predetermined impact load to the front end of the load transfer member in a rearward direction of the vehicle body, the displacing region of the front side frame will push against a lateral side of a mounting base supporting the power unit to push the power unit toward the opposite front side frame.

12. The front vehicle body structure according to claim 9 , wherein the front end of the load transfer member is positioned in an opposing and spaced relationship with a rear surface of a front bumper beam.

13. The front vehicle body structure according to claim 9 , wherein the displacing region of the front side frame is located further rearward of the fixed position.

14. The front vehicle body structure according to claim 9 , wherein the separator substantially partitions an internal cross-section of the front side frame.

15. The front vehicle body structure according to claim 9 , wherein the separator blocks an internal cross-section of the front side frame.

16. A front vehicle body structure comprising:

a front side frame disposed at a front of a vehicle body on each side of a power unit in a vehicle body width direction, the front side frame extending substantially in a fore-and-aft direction of the vehicle body; and

a load transfer member disposed outside the front side frame in the vehicle body width direction, near a front end of the front side frame, a rear end of the load transfer member being fixed to an outer lateral side of the front side frame in the vehicle body width direction at a fixed position, the fixed position being located forwardly of a center position of the power unit in the fore-and-aft direction, a front end of the load transfer member being disposed forwardly of the rear end of the load transfer member in the fore-and-aft direction and outwardly of the rear end of the load transfer member in the vehicle body width direction,

wherein the front vehicle body structure is configured such that, upon input of a predetermined impact load to the front end of the load transfer member in a rearward direction of the vehicle body, a displacing region of the front side frame located at or rearward of the fixed position will be displaced toward a lateral side of the power unit, and

the front vehicle body structure further comprising a separator positioned adjacent to the rear end of the load transfer member and configured to enhance the stiffness of the front side frame at the displacing region for promoting the transfer of an impact load from the load transfer member to the power unit.
