A front body of a vehicle has a pair of box shaped kick-down front side frames, which extend in a lengthwise direction, from front to back, of the vehicle, for forming an engine receiving volume. The kick-down front side frame is contituted by a straight front side frame portion and a kick-down frame portion by which the side frame is connected to a floor frame. A reinforcement, placed within the box-shaped kick-down fornt side frame so as to extend across the straight front side frame portion and kick-down frame portion, is provided with a crushable notch, near a transitional portion of the kick-down front side frame located between the straight front side frame portion and kick-down frame portion. The crushable notch allows the kick-down front side frame to be crushed, or bent, at the transitional portion in a desired pattern of deformation during a collision of the vehicle.
