To provide a vehicular body structure capable of suppressing a reduction of sound insulation performance and of thermal insulation performance at a joint portion between an edge of a hollow double-wall panel and a joint mating member even though a core member is not filled in the joint mating member.SOLUTION: In the vehicular body structure 1, a hollow double-wall panel 5 is formed by continuously joining respective edges of two walls 51 and 52 and by filling a core member 53a in a closed space Sa between the two walls 51 and 52. The core member 53a is filled in the interior of an edge 55 of the hollow double-wall panel 5. With the edge 55 of the hollow double-wall panel 5 being joined with an upper surface 32a of a side sill 3, the core member 53a that is filled in the edge 55 of the hollow double-wall panel 5 covers the upper surface 32a of the side sill 3.SELECTED DRAWING: Figure 3
【課題】連結相手部材の内部にコア材が充填されていなくても、中空二重壁パネルの縁部と連結相手部材との連結部分で、防音性及び断熱性が低下することを抑制できる車体構造を提供する。【解決手段】この車体構造1では、中空二重壁パネル5は、2つの壁部51,52の周縁部同士が連接されて2つの壁部51,52の間の閉空間Saにコア材53aが充填されて構成され、中空二重壁パネル5の縁部55の内部までコア材53aが充填され、中空二重壁パネル5の縁部55がサイドシル3の上面32aに連結された状態で、中空二重壁パネル5の縁部55に充填されたコア材53aがサイドシル3の上面32aを被覆する。【選択図】図3
