Zusammenfassung:To allow a closed cross sectional structure part and an opened cross sectional structure part to be appropriately provided in side frames.SOLUTION: Side frames 10 provided at both end parts in a width direction of a vehicular seat have: a closed cross sectional structure part 10a constituting one end part in a frame extension direction and an opened cross sectional structure part 10a constituting a part continuous to the closed cross sectional structure part 10a in the frame extension direction. Further, a clearance Q formed resulting from discontinuity of the continuous part in the cross section of the opened cross sectional structure part 10b becomes larger in a separated region 10y disposed at a position separated from the closed cross sectional structure part 10a in the frame extension direction than in an adjacent region 10x adjacent to the closed cross sectional structure part 10a in the frame extension direction, of the opened cross sectional structure part.SELECTED DRAWING: Figure 6 【課題】サイドフレーム中に閉断面構造部と開断面構造部とを適切に併存させる。【解決手段】車両用シートの幅方向両端部に設けられたサイドフレーム10が、フレーム延出方向一端部をなす閉断面構造部10aと、フレーム延出方向において閉断面構造部10aと連続する部分をなす開断面構造部10bと、を有する。また、開断面構造部10bの断面において連続している部分が途切れることで形成された隙間Qが、開断面構造部のうち、フレーム延出方向において閉断面構造部10aと隣接する隣接領域10xよりも、フレーム延出方向において閉断面構造部10aから離れた位置に在る離間領域10yにおいてより大きくなっている。【選択図】図6
