Vehicle body structure made of extruded members

摘要

In a space frame type vehicle body structure, a floor member has a side sill inner half securely attached along each side edge thereof, and a side frame has a side sill outer half securely attached along a lower edge thereof, and these two halves are provided with mutually cooperating snap fit arrangement. Because the floor member and the side frame are individually provided with a sufficient rigidity, and they can be temporarily secured each other simply by pushing them against each other, they can be welded together with a high dimensional precision without requiring any massive or complex clamping fixture.
