を解消する車体構造を提供するものである。However, in such a vehicle body structure, if the rigidity of the stopper is too large, the impact force of the frame is directly transmitted to the vehicle body, so that the vehicle body suddenly decelerates. Then, the occupant is largely moved forward. Conversely, if the rigidity of the stopper is insufficient,
Since the deformation of the stopper becomes large and the vehicle body gets over the deformed stopper, finally, the mount portion is damaged, and problems such as the inability to restrict the forward movement of the vehicle body occur. Therefore, the present invention provides a vehicle body structure that solves the above-mentioned problems.

させる。When a vehicle has a frontal collision, a large negative acceleration acts on the side members 22 constituting the frame by receiving the impact force. In the vehicle body 10 supported on the frame via an elastic member, the vehicle body 10 moves forward by the action of the inertial force F 1 , and the protruding portion 12 is connected to the first stopper member 52 of the stopper device 40 as shown in FIG. collide. Due to this collision, a negative acceleration is also generated in the vehicle body 10, and the restraint device for the seat belt is operated to activate the sensor of the airbag.

ーパー部６２に当接する。The first stopper member 50 undergoes plastic deformation due to the inertial force of the vehicle body and is crushed. The impact energy is absorbed while the first stopper member 50 undergoes plastic deformation. As the deformation of the first stopper 50 progresses, as shown in FIG. 6, the back surface of the wall portion 52 of the first stopper member 50 finally comes into contact with the tapered portion 62 of the second stopper member 60.

Thereby, the negative acceleration acting on the occupant can be suppressed to a small value. The peak P 2 also can be lower than that P 1 of the conventional curve, it is possible to reduce the impact force applied to the vehicle body. As the plastic deformation of the first stopper member progresses,
Curve drag draws a curve right downward as indicated by the region S 2.

At the time of a frontal collision of the vehicle, a stopper device provided on the frame is restrained by a two-stage stopper member in order to restrict the vehicle body moving forward by inertia force against the frame stopped at a large negative acceleration. The rise of the acceleration can be reduced. Therefore, the impact applied to the occupant is reduced. In addition, the moving amount of the vehicle body is within the durability range of the mounting device of the vehicle body, so that a living space for the occupant can be secured.
