Abstract: A front body structure of a vehicle, in which a power plant is installed, includes a reinforcement secured to a mounting portion of a wheel housing located where an engine mounting bracket is attached. The front body structure also includes another reinforcement, for connecting the reinforcement to a suspension tower, which connects the reinforcement to the wheel housing. The other reinforcement is smaller in plate thickness than the reinforcement so as to absorb impact force applied to the front body during a front end collision. A front frame reinforcement is secured to a front side frame so as to reinforce a portion of the front side frame at a location in which a cut-away portion is formed so as to compensate for a decrease in structural strength of the front side frame. A connecting member connects the power-plant to a rigid structural member so as to suppress a movement of the power-plant during a front end collision.

Abstract: The impact sensor is mounted to the front portion of the vehicle body to operate at a high degree of responsiveness. The impact load is entered into the front frame to the bumper in such a manner that the input point of input of the impact load is offset by a given distance upwards above the vertically central line of the front frame. To a lower front end portion of the front frame is joined the cross member so as to make rigidity at the upper portion of the front frame equal to that at the lower portion thereof. The impact sensor is mounted to the front frame in such a forwards inclined state with respect to the horizontal direction of the vehicle body that the direction of the impact sensor in which the impact of the crash is sensed approaches the horizontal direction.
