To obtain a headrest support structure which enables reduction of concentration of stress in a stay holding member.SOLUTION: A headrest support structure 10 includes: an upper frame of a seat back frame; and stay holding members 20. The upper frame has upper insertion holes and lower insertion holes. The stay holding member 20 has a shaft part 26 provided with a cylinder hole 22 in which a headrest stay is inserted and held. The stay holding member 20 includes an upper claw part 30 and a lower claw part 32 for preventing removal which are disposed at positions corresponding to a lower end of the upper insertion hole and a lower end of the lower insertion hole in a state that the shaft part 26 is inserted into the upper insertion hole and the lower insertion hole. The stay holding member 20 includes slits 34 disposed at both circumferential sides of the upper claw part 30 and the lower claw part 32 and extending from an upper end of the upper claw part 30 to a lower end of the lower claw part 32. The stay holding member 20 includes an installation part 36 which divides the slits 34 vertically.SELECTED DRAWING: Figure 5

    【課題】ステー保持部材における応力の集中を低減させることができるヘッドレスト支持構造を得る。【解決手段】ヘッドレスト支持構造10は、シートバックフレームのアッパフレームと、ステー保持部材20とを備える。アッパフレームは上挿通孔及び下挿通孔を有する。ステー保持部材20は、内部にヘッドレストステーを挿入して保持する筒孔22が形成された軸部26を有する。ステー保持部材20は、軸部26が上挿通孔及び下挿通孔に挿入された状態で、上挿通孔の下端及び下挿通孔の下端に各々対応する位置に配置された抜け止め用の上爪部30及び下爪部32を備える。ステー保持部材20は、上爪部30及び下爪部30の周方向両側に各々配置され、上爪部30の上端から下爪部32の下端まで延在されたスリット34を備える。ステー保持部材20は、スリット34を上下に分割する架設部36を備える。【選択図】図5
