To provide a panel body and hollow structure making it possible to readily ensure reinforcement performance of a vehicle even when plural reinforcement members are employed.SOLUTION: A first reinforcement member 21 of a panel body 11 to be employed for the purpose of structuring a vehicle includes a first foamable member 22 serving as a first foamable body, a first cover member 23 shielding the first foamable member 22, and a first fixation member 24 that fixes the first cover member 23 to a constituent panel P1. A second reinforcement member 31 includes a second foamable member 32 serving as a second foamable body, a second cover member 33, and a second fixation member 34. The first foamable member 22 and second foamable member 32 are disposed to form a foamable body having a junction foamable part that includes in its orthogonal section, which is orthogonal to a longitudinal direction, at least part of a composition plane between the first foamable body and second foamable body, and a non-junction foamable part that does not include the composition plane in its orthogonal section. The panel body 11 forms an orthogonal section, which is smaller than the orthogonal section of the junction foamable part, in the non-junction foamable part.SELECTED DRAWING: Figure 4
【課題】複数の補強用部材を用いる場合であっても車両の補強性能を容易に確保することのできるパネル体及び中空構造体を提供する。【解決手段】車両を構成する用途に用いられるパネル体11の第1補強用部材21は、第1発泡体となる第1発泡性部材22と、第1発泡性部材22を覆う第1カバー部材23と、第1カバー部材23を構成パネルP1に固定する第1固定部材24とを備える。第2補強用部材31は、第2発泡体となる第2発泡性部材32と、第2カバー部材33と、第2固定部材34とを備える。第1発泡性部材22及び第2発泡性部材32は、長手方向に直交する直交断面内に第1発泡体と第2発泡体との接合面の少なくとも一部を含む接合発泡部と、直交断面内に接合面を含まない非接合発泡部とを有する発泡体を形成するように配置される。パネル体11は、接合発泡部の直交断面よりも小さい直交断面を非接合発泡部に形成するように構成される。【選択図】図4
