To solve the problem in which all portions of a headrest stay has the same cross-sectional structure and most of the portions has excessive specifications for the required bending strength, which causes waste of materials and high cost.SOLUTION: For a pair of left and right legs for a headrest stay, an area for a predetermined length of sliding portions of support opening ends has a double pipe structure. Bent portions of a bridge have a double pipe structure. Inner pipes are inserted into these portions and secured in a crimped manner. For each leg and the bridge of the headrest stay, it is possible to select any member that suits the function and required strength so that cost and quality advantages for the headrest stay can be provided.SELECTED DRAWING: Figure 1

    【課題】 ヘッドレストスティが全部位に応じて同一断面構造で、必要な曲げ強度においては大部分がオーバスペックの状態となり、材料の無駄、高コストとなっていた。【解決手段】ヘッドレストスティの左右一対の脚部でサポート開口端の摺接部の所定長さ範囲について二重管構造とする。また、ブリッジ部の屈曲部にも二重管構造とする。これらの部位には内管を挿入し、カシメ固定した。ヘッドレストスティの各脚部とブリッジ部とにおいて、それぞれの機能や要求強度に適合した部材を任意に選択することが可能となり、ヘッドレストスティの品質やコストに優位性を付与できる。【選択図】 図1
