To facilitate insertion of lower end parts of left and right side frames of a back frame to a connection space of a support bracket.SOLUTION: A structure for fitting a back frame into a vehicular seat comprises: a support bracket 25 made of metal in which an upper end is open and a connection space is formed therein; and a back frame made of resin having side frames 50 of which lower end parts 59 are inserted from above to the connection space 36 of the support bracket. The lower end part of the side frame comprises two parts 57 to be fixed that are fixed respectively at two places of the support bracket and mutually separated in a front and rear direction. When a straight line passing the two parts to be fixed is defined as a reference line SL2, a distance LB between one specification part 55R that is a portion of a lower edge part 55 of the side frame, and the reference line is longer than a distance LF between a site excluding the specification part of the lower edge part, and the reference line.SELECTED DRAWING: Figure 7

    【課題】バックフレームの左右のサイドフレームの下端部を、支持ブラケットの接続空間に簡単に挿入できるようにする。【解決手段】上端が開口すると共に内部に接続空間が形成された金属製の支持ブラケット25と、支持ブラケットの接続空間36に下端部59が上方から挿入されるサイドフレーム50を有する樹脂製のバックフレームと、を備え、サイドフレームの下端部が、支持ブラケットの2か所にそれぞれ固定され且つ互いに前後に離れた2つの被固定部57を備え、2つの被固定部を通る直線を基準線SL2と定義した場合に、サイドレームの下縁部55の一部である一つの特定部55Rと基準線との間の距離LBが、下縁部の特定部を除く部位と基準線との間の距離LFより長い。【選択図】図7
