To obtain a headrest bush which can easily adjust a height of a rib for suppressing rattling of a stay of a headrest and can be easily assembled to a seat back frame, and a vehicle seat comprising the same.SOLUTION: A headrest bush 30 has a cylindrical part 36 which is inserted into an insertion hole formed at an upper end part of a frame of a seat back and inside which a stay of a headrest is inserted. A pair of front ribs 50A, 50B are so formed on a front face of the cylindrical part 36 as to be arranged in a circumferential direction, and a pair of rear ribs are so formed on a rear face of the cylindrical part 36 as to be arranged in the circumferential direction. On both sides in the circumferential direction with respect to the pair of front ribs 50A, 50B, a pair of slits 48A, 48B, which extend in an axial direction of the cylindrical part 36, are formed. The pair of front ribs 50A, 50B are pressed against an inner peripheral surface of the insertion hole, whereby a part between the pair of slits 48A, 48B bend to a rear side and closes a gap between itself and the stay.SELECTED DRAWING: Figure 4

    【課題】ヘッドレストのステーのガタつきを抑制するためのリブの高さ調整が容易で且つシートバックフレームへの組み付けが容易なヘッドレストブッシュ及びこれを備えた車両用シートを得る。【解決手段】ヘッドレストブッシュ30は、シートバックのフレームの上端部に形成された挿入孔に挿入され、内側にヘッドレストのステーが挿入される筒状部36を有する。筒状部36の前面には、一対の前側リブ50A、50Bが周方向に並んで形成されており、筒状部36の後面には、一対の後側リブが周方向に並んで形成されている。一対の前側リブ50A、50Bに対する周方向の両側には、筒状部36の軸方向に延びる一対のスリット48A、48Bが形成されている。一対の前側リブ50A、50Bが上記挿入孔の内周面に押し当てられることで、一対のスリット48A、48Bの間の部位が後方側へ撓んでステーとの間の隙を詰める。【選択図】図4
