To suppress reduction in strength by undulation in press molding of long fibers in the vicinity of a tip of a plate-like member of a fiber-reinforced resin material having long fibers.SOLUTION: A plate-like member 1 is formed of a non-continuous fiber-reinforced resin having long fibers. A hole part 3 is provided on a plane part 2 of the plate-like member 1, and a side wall 5 is integrally formed on a semicircular end 2c of the plane part 2 positioned near the hole part 3. The side wall 5 is arranged so as to extend along the outer periphery in a region between an opening edge 3a closer to a tip 2d in the hole part 3 and the tip 2d.SELECTED DRAWING: Figure 1
【課題】長繊維を有する繊維強化樹脂材の板状部材の先端部の近傍において、長繊維のプレス成形時のうねりによる強度低下を抑制する。【解決手段】板状部材1は、長繊維を有する不連続繊維強化樹脂で形成される。板状部材1の平面部2には、穴部3が設けられ、穴部3の近くに位置する平面部2の半円状端部2cには、側壁5が一体的に形成されている。側壁5は、穴部3における先端部2dに近い方の開口縁3aと先端部2dとの間の領域に、外周に沿って延びて配置される。【選択図】図1
