PROBLEM TO BE SOLVED: To quickly decelerate a vehicle by transmitting inertia force toward a front side of the vehicle, applied to a power unit in the initial stages of head-on collision of the vehicle to a sub-frame. SOLUTION: A front mount part 24 of the sub-frame 20 is provided near a front side of the vehicle of a drive shaft 50 extending from the power unit 40 supported on a front side member 12 through an engine mount 48. The power unit 40 is inertially moved to the front side of the vehicle relative to the sub-frame 20 in the initial stages of the head-on collision of the vehicle, and the drive shaft 50 is abutted on a rear side of the vehicle of the front mount part 24 of the sub-frame. Thereby, a load transmission route connected to the sub-frame 20, the front mount part 24, the drive shaft 50 and the power unit 40 is formed. COPYRIGHT: (C)2007,JPO&INPIT
