Summary:PROBLEM TO BE SOLVED: To provide a seat frame which can suppress generation of abnormal sound when a sector gear rotates with height adjustment operation.SOLUTION: The seat frame of a vehicle seat is provided with a seat cushion frame for structuring a frame of a seating part of the vehicle seat, and a height adjustment mechanism 40 which is connected to the seat cushion frame and a rail mechanism of the vehicle seat and adjusts a height of the seat cushion frame. The height adjustment mechanism 40 includes a sector gear 41a rotating with height adjustment operation, a link which vertically moves the height of the seat cushion frame by interlocking with the rotation of the sector gear 41a, and a restriction member 60 which abuts on the sector gear 41a and restricts movement of the sector gear 41a. At least one of parts where the sector gear 41a and the restriction member 60 abut on each other has a tapered shape.SELECTED DRAWING: Figure 19 【課題】高さ調整操作に伴ってセクターギアが回動する際の異音の発生を抑制できるシートフレームを提供する。【解決手段】車両用シートのシートフレームは、車両用シートの着座部分のフレームを構成するシートクッションフレームと、シートクッションフレームと車両用シートのレール機構とに連結され、シートクッションフレームの高さを調整する高さ調整機構40と、を備える。高さ調整機構40は、高さ調整操作に伴って回動するセクターギア41aと、セクターギア41aの回動に連動してシートクッションフレームの高さを上下動させるリンクと、セクターギア41aと当接し、セクターギア41aの動きを規制する規制部材60と、を有する。セクターギア41aと規制部材60が互いに当接する部分のうち少なくとも一方をテーパー形状とした。【選択図】図19
