To improve rigidity of a portion where side frame pieces overlap each other in a side frame.SOLUTION: In a vehicular sheet including a seat back frame, a side frame (10) of the seat back frame has a first side frame piece (20) and a second side frame piece (30) which partially overlap each other in its extension direction, and in an overlapping portion (40) where both the first side frame piece (20) and the second side frame piece (30) overlap each other in the side frame (10), the side frame pieces overlap each other in a state where a plurality of closed regions (41 and 42) surrounded by both of the side frame pieces is formed in a cross section of the overlapping portion (40) intersecting with the extension direction of the side frame (10).SELECTED DRAWING: Figure 4

    【課題】サイドフレームにおいてサイドフレーム片同士が重なり合っている部分の剛性を向上させる。【解決手段】シートバックフレームを備える車両用シートにおいて、シートバックフレームのサイドフレーム(10)は、その延出方向において部分的に重なり合った第一サイドフレーム片(20)及び第二サイドフレーム片(30)を有し、サイドフレーム(10)において第一サイドフレーム片(20)及び第二サイドフレーム片(30)の双方が重なり合った重なり部分(40)では、サイドフレーム(10)の延出方向と交差する重なり部分(40)の断面において双方のサイドフレーム片に囲まれて閉じた閉領域(41,42)が複数形成された状態でサイドフレーム片同士が重なり合っている。【選択図】図4
