To provide a headrest support structure in that deformation of a headrest support part is preferably inhibited and a headrest is not largely tilted backwardly even when force is applied to the headrest backwardly.SOLUTION: A headrest support structure includes: an upper panel 5 extending in a width direction at an upper part of a seat back frame and having a U-shaped sleeve support part, which includes an upper wall part 5a and a lower wall part 5c vertically facing each other and has a vertical cross sectional shape open toward a side opposite to a seating surface, an upper hole 5a1 formed on the upper wall part 5a and a lower hole 5c1 formed at a position corresponding to the upper hole 5a1 on the lower wall part 5c; a tubular collar 61 having a through hole 61a in which the through hole 61a is arranged between the upper wall part 5a and the lower wall part 5c so as to communicate with the upper hole 5a1 and the lower hole 5c1; and a sleeve 71 inserted into the upper hole 5a1, the through hole 61a, and the lower hole 5c1 from above, and allowing a rod-like leg part 81 of a headrest ST3 to be inserted therein.SELECTED DRAWING: Figure 2

    【課題】ヘッドレストに対し後方へ力が加わっても、ヘッドレスト支持部の変形が良好に抑制されヘッドレストが後方へ大きく傾倒することがないヘッドレスト支持構造を提供する。【解決手段】シートバックフレームの上部において幅方向に延在し、上下に対向する上壁部5aと下壁部5cとを含んで縦断面形状が着座面とは反対側に開放したコ字状のスリーブ支持部を有する上部パネル5と、上壁部5aに形成された上部孔5a1及び下壁部5cにおいて上部孔5a1に対応した位置に形成された下部孔5c1と、貫通孔61aを有する管状であって、上壁部5aと下壁部5cとの間に、貫通孔61aが上部孔5a1及び下部孔5c1に連通するよう配置されたカラー61と、上部孔5a1と貫通孔61aと下部孔5c1とに対し上方から挿通されヘッドレストST3の棒状脚部81を挿入可能なスリーブ71と、を備えた。【選択図】図2
