A vehicle front body structure includes a pair of front side frames each of which has, at a rear portion thereof, an easily deformable portion that is easily deformable during a collision, a support frame for mounting a unit box thereon, which has a pair of rear legs that are fixed to the easily deformable portions of the pair of front side frames, and a pair of front legs that are fixed to portions of the pair of front side frames, the portions being located in the front as viewed from the easily deformable portions. Displacement allowing spaces for allowing displacement of the unit box during a collision are provided near side portions of the unit box adjacent to the rear legs.

What is claimed is: 1. A vehicle front body structure comprising: a pair of front side frames located at a front of the vehicle, each of the front side frames has a front portion and a deformable portion to the rear of the front portion that is configured to more easily deform when compared to the front portion during a passenger's side offset collision; a support frame with a unit box mounted thereon, the support frame being disposed above the front side frames and has a rear middle portion with a pair of rear legs that obliquely and downwardly extend from the rear middle portion and are fixed to the deformable portions of the pair of front side frames, and a front middle portion with a pair of front legs that obliquely and downwardly extend from the front middle portion and are fixed to the front portions of the pair of front side frames; a driving motor disposed under the unit box; a first set of high voltage lines disposed on a driver's side of the vehicle and extending from the unit box to the driving motor; a fuel cell stack behind the unit box; a second set of high voltage lines extending from the unit box, near a rear corner thereof adjacent to one of the rear legs on the driver's side of the vehicle, to the fuel cell stack; displacement allowing spaces for allowing displacement of the unit box during a passenger's side offset collision disposed near side portions, on the driver's side of the vehicle, of the unit box adjacent to the rear legs; and another space disposed near a side portion, on the driver's side of the vehicle, of the unit box adjacent to one of the front legs, the space being narrower in the lateral direction of the vehicle than each of the displacement allowing spaces, wherein the first set of high voltage lines extend from a portion of the unit box adjacent to the space that is narrower than each of the displacement allowing spaces.
