A rear apron panel is provided between a suspension tower and a dash panel. A vertical branch brace is provided to extend upwardly from a front side frame along an inner face of a suspension tower to form a closed cross section with a rear portion of the suspension tower. A deformation restraint member interconnects the apron frame and the vertical branch brace. Accordingly, there is provided a vehicle-body front structure which can restrain the apron frame from deforming outwardly in the vehicle width direction in the vehicle frontal collision to prevent the dash panel from moving back into the vehicle compartment too much.

Vehicle-body front structure

A battery is arranged at a specified position which is located on an outside of a front side frame in a vehicle width direction and between a front wheel and a crush can in a vehicle longitudinal direction. Accordingly, the battery can be positioned properly at a front portion of a vehicle so that the battery may not receive any improper thermal influence from an engine or a motor and not hurt the function of impact absorption in a vehicle frontal collision.

Battery arrangement structure of vehicle

A hinge reinforcement is provided at a hinge pillar at a specified position which corresponds to an upper door-hinge attachment portion. Attachment portions which extend toward a hinge pillar inner and are attached to this hinge pillar inner are provided at the hinge reinforcement which corresponds to the upper door-hinge attachment portion. A branch frame and a gusset member which transmit an impact load inputted from a front side frame extending in a vehicle longitudinal direction to the attachment portions via the hinge pillar inner are provided so as to extend from the front side frame. Accordingly, the impact load inputted to the vehicle body at the vehicle collision can be properly transmitted to the vehicle rear portion, so that the deformation of the vehicle compartment can be restrained surely.
