A vehicle body structure, includes: a pair of front side members, front ends of which are joined to both ends of a front bumper via impact absorbing portions, respectively; front-side-member upper members, which are arranged above the front side members, and front ends of which are connected to the front side members, respectively; front-side-member lower members, which are arranged below the front side members, and front ends of which are connected to the front side members, respectively; and a dash cross member, which extends in a widthwise direction of a vehicle body, and to which rear ends of the front-side-member lower members are joined. The dash cross member includes wall portions with which parts of the rear ends of the front-side-member lower members can be brought in contact, on a rear side of the vehicle body.

Vehicle body structure

A body framework construction, includes: a rear seat cross member, extending in a transverse direction of a vehicle, in a rear part of a body in a lower part of a passenger compartment; a dash cross member upper, extending in the transverse direction, in a front part of the passenger compartment; and a backbone, configured into a thin, long shape having a closed cross section, and extending in a longitudinal direction of the vehicle. A front end portion of the backbone is connected to the dash cross member upper via a gusset, and a rear end portion of the backbone is joined to the rear seat cross member. The gusset is deformed more easily than the backbone relative to a force from a front.

Body framework construction

A deck cross-member comprises a first pipe, a joint member, and a second pipe. The first pipe is configured to support a steering unit. The first pipe has a cross section that is uniform along the axial direction as viewed in a plane perpendicular to the axial direction. The joint member is inserted in the first pipe and secured to the first pipe. The joint member incorporates a receptacle unit. The second pipe is inserted in the receptacle unit of the joint member, thus secured to the joint member. The second pipe has a cross section that is uniform along the axial direction as viewed in a plane perpendicular to the axial direction.

Deck cross-member and method of manufacturing a deck cross-member

A vehicle body structure of the present invention includes a side-frame disposed to extend along one direction, a side sill disposed to extend in the one direction alongside the side-frame on the outside thereof, a cross member disposed to extend in a direction in which the cross member intersects with the side-frame and which is joined to a side portion of the side-frame to form a vehicle body together with the side-frame, and a gusset provided between the side-frame and the side sill on a longitudinal extension of the cross member, which extends in a smaller cross section than that of the cross member from a joint portion where the cross member is joined to the side-frame until the gusset comes into abutment with the side sill while passing through the side-frame and which is formed as an integral part of the cross member.
