  • Patent number: 6428074
    Abstract: A construction is provided for fastening a plurality of members which thermally expand and contract together to a base member with a screw member, in such a manner that those members do not interfere with each other when they thermally expand or contract. An interference that would otherwise be generated between a plurality of members to be fastened together when the respective members thermally expand and contract can be prevented with a simple construction by interposing an interference preventing spacer member between the respective members. The spacer member is positioned in a radial direction relative to a screw portion. With one member, the fastened portion where the members are fastened together functions as a reference point for absorbing the thermal expansion and contraction. With the other member, an elongate hole is used at this fastened portion for absorbing the thermal expansion and contraction. Accordingly, the single fastened portion allows fastening corresponding to the respective members.

  • Patent number: 6382709
    Abstract: A vehicle front part structure includes right and left front side frames provided rightwardly and leftwardly of and extending longitudinally of a vehicle body. A front bumper beam is attached to front ends of the right and left front side frames and extends transversely of the vehicle body. Right and left substays extend downwardly from front parts of the right and left front side frames. The right and left substays have lower parts connected to each other through a front lower cross member. Each of the right and left substays has first portions coupled through fastening members to and has second portions coupled through fillet welding to the respective front parts of the right and left front side frames.

  • Patent number: 6048022
    Abstract: A hood or trunk lid is a blow-molded article and includes an outer skin and a stiffener integral with the outer skin. The stiffener has a tub-like molded portion which extends in a widthwise direction of a vehicle body and protrudes toward the outer skin. A ridge of the tub-like molded portion is spaced apart from the outer skin, so that the hood or trunk lid is folded from a start point provided by the tub-like molded portion by a shock force from a collision.

  • Patent number: 6022070
    Abstract: A vehicle body frame structure is comprised of plurality of loop-shaped members each formed by a hollow pieces extruded from a light alloy. Each loop-shaped member is polygonal in cross section. The vehicle body frame structure is partly formed by a plurality of such loop-shaped members joined sidewise together. Each loop-shaped member is comprised of at least two hollow extruded pieces joined together by a core coupling or a split muff coupling. Part of each loop-shaped member is stepped so that it can be joined with a companion loop-shaped member by mating the stepped portions of the two loop-shaped members one over the other.

  • Patent number: 5765906
    Abstract: 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.
