PROBLEM TO BE SOLVED: To provide a panel which can prevent occurrence of cracks and is excellent in strength.SOLUTION: A panel 20 has a folded part 41 which is formed by being folded from an end edge part 35 of a curved part 31 to a side of a surface 33 continuous with a rear face 23 of a main plate part 21 in the curved part 31, and has such a curved shape that a surface 42 continuous with a surface 32 of the opposite curved part 31 projects. The panel 20 can prevent occurrence of cracks because of decreasing a degree of bending of the end edge part 35 of the curved part 31. The curved part 31 and the folded part 41 have an entirely curved shape which is a so-called egg shell shape, and accordingly the strength is improved.SELECTED DRAWING: Figure 2
【課題】クラックの発生を防止でき、かつ強度に優れたパネルを提供する。【解決手段】湾曲部３１の端縁部３５から、湾曲部３１における主板部２１の裏面２３と連続する面３３側へ折り返されてなり、かつ対向する湾曲部３１の表面３２と連続する面４２が凸となる湾曲形状の折り返し部４１を備えているパネル２０は、湾曲部３１の端縁部３５の屈曲度合いが減少するためにクラックの発生を防止でき、湾曲部３１と折り返し部４１が全体的に湾曲した形状となり、いわゆる卵殻形状となるため強度が向上する。【選択図】図２
