Abstract: A suspension subframe is secured to an insert member embedded in a core material of an inclined wall of a dash panel. The core material is formed from corrugated plate having a multiplicity of concave-convex portions extending in the fore-and-aft direction. One apex of the insert member is oriented in the vehicle width direction, and two sides of the insert member, proximate the apex, abut against the core material. When a load in the vehicle width direction is inputted from the suspension system into the subframe, it is possible, by absorbing the load by dispersing it from the two sides sandwiching the apex of the insert member toward the core material of the inclined wall of the dash panel, to enhance the support rigidity of the subframe with respect to the inclined wall of the dash panel without excessively complicating the structure of the insert member.

Abstract: Since an inclined face extending in the fore-and-aft direction is formed in an inner skin on a border between a floor panel and a side sill in a fiber-reinforced plastic cabin for a vehicle, when a bending moment that works so as to collapse the side sill inwardly in the vehicle width direction is applied by the collision load of a side collision, it is possible, without increasing the number of cross members or increasing the height of the cross member, to prevent the side sill from collapsing. Furthermore, since the inclined face of the inner skin and an outer skin are joined to a frame member extending in the fore-and-aft direction, it is possible to suppress deformation of the inclined face and to further reliably prevent the side sill from collapsing by transmitting the bending moment to the outer skin via the frame member.

Abstract: A subframe supporting a suspension system is secured to an insert member embedded in a core material of an inclined wall of a dash panel. Since the core material is formed from the corrugated plate having a large number of concave-convex portions extending in the fore-and-aft direction, one apex of the insert member, is oriented in the vehicle width direction, and two sides sandwiching the apex abut against the core material, when a load in the vehicle width direction is inputted from the suspension system into the subframe, it is possible, by absorbing the load by dispersing it from the two sides sandwiching the apex of the insert member toward the core material of the inclined wall of the dash panel, to enhance the support rigidity of the subframe with respect to the inclined wall of the dash panel without complicating the structure of the insert member.

Abstract: To achieve efficient and proper transmission of an impact load from a floor frame on one side of a vehicle body to a floor frame on the other side to thereby protect a battery unit from damage, an automotive floor structure includes a first cross member upper and a first cross member lower. the first cross member upper extends in a lateral direction of the vehicle body and has ends attached to left and right side sills, respectively. The first cross member lower extends in the lateral direction below a front floor panel at a position under the first cross member upper, and has ends secured to the left and right floor frames, respectively. The first cross member upper and the first cross member lower vertically sandwich the battery unit therebetween.

Abstract: A fiber-reinforced resin member is provided in which a mounting hole is formed in a plate material reinforced by embedding a fiber in a thermosetting resin, and another member is fixed to the fiber-reinforced resin member (11) by using a securing member fixed into the mounting hole. An insert member having the mounting hole formed therein is connected to an opening formed in the plate material. The insert member is formed into a tubular shape by impregnating a fiber with a thermosetting resin, and hot pressed together with the plate material by using a mold. Such arrangement does not require drilling the mounting hole in a fiber-reinforced resin member, and also does not require strictly aligning the position of the opening of the plate material with respect to a mounting hole molding pin of the mold when setting the uncured plate material in an interior of the mold.
