  • Front portion structure of vehicle frame
    Patent number: 6460889
    Abstract: A stopper 1 is fixedly mounted on and projects from an outer surface of that portion of a side frame 7 disposed in the vicinity of a front wheel 14. A reinforcement 2 is mounted on an inner surface of that portion of the side frame 7, on which the stopper 1 is mounted, thereby reinforcing the stopper 1. At the time of a collision of a vehicle, a rear side 17 of an outer periphery of the front wheel 14 strikes against the stopper 1, and also the movement of the stopper 1 is prevented by the reinforcement 2, thereby limiting the movement of the front wheel 14. Therefore, the deformation of the side frame 7 and so on toward the vehicle frame is reduced.
