PROBLEM TO BE SOLVED: To improve rigidity of an outer peripheral edge part of a panel material, and improve rigidity of an entire seat back frame.SOLUTION: A reinforcement structure of a seat back frame 10 includes a panel material 20 and a frame material 30 joined to the panel material 20. The panel material 20 has an outer circumference flange 25 formed by folding an outer peripheral edge part of the panel material 20. The outer circumference flange 25 has a plurality of outer circumference beads 26... arranged at intervals in a circumferential direction of the panel material 20. Thereby, rigidity of the outer peripheral edge part of the panel material can be synergistically improved by both the outer circumference flange and the plurality of outer circumference beads, and thus, rigidity of the seat back frame can be improved.SELECTED DRAWING: Figure 4

    【課題】パネル材の外周縁部における剛性を向上させて、シートバックフレーム全体の剛性を向上させる。【解決手段】パネル材20と、当該パネル材20に対して接合されたフレーム材30と、を備えたシートバックフレーム10の補強構造であって、パネル材20は、当該パネル材20の外周縁部が折り曲げられて形成された外周フランジ25を有しており、外周フランジ25には、パネル材20の周方向に間隔を空けて配置された複数の外周ビード26…が形成されている。これにより、外周フランジと複数の外周ビードの双方によって相乗的にパネル材の外周縁部の剛性を向上させることができ、延いては、シートバックフレームの剛性を向上させることができる。【選択図】図4
