To improve bond strength between two frames constituting a hollow frame.SOLUTION: A vehicular seat comprises a first frame 70 and a second frame 80 constituting a hollow frame with a closed cross section. The first frame 70 has two first side walls (71) opposing to each other in a first direction and a first bottom wall connecting the first side walls to each other. The second frame 80 has two second side walls (82) opposing to each other in the first direction and a second bottom wall connecting the second side walls to each other and opposing to the first bottom wall, in a second direction. An edge at the opposite side of the first bottom wall of one first side wall 71 has a first protruding edge part E11 joined to one second wall 82, and a first base edge part E12 arranged closer to the first bottom wall than the first protruding edge part E11, which is joined to the one second side wall 82. A welding mark WP at which the first protruding edge part E11 is joined to the second side wall 82 and a welding mark WP at which the first base edge part E12 is joined to the second side wall 82 are arranged at different positions in the second direction.SELECTED DRAWING: Figure 3 【課題】中空フレームを構成する２つのフレームの接合強度を向上させること。【解決手段】乗物用シートは、閉断面の中空フレームを構成する第１フレーム７０および第２フレーム８０を備える。第１フレーム７０は、第１方向に対向する２つの第１側壁（７１）と、第１側壁を連結する第１底壁を有する。第２フレーム８０は、第１方向に対向する２つの第２側壁（８２）と、第２側壁を連結し、第１底壁と第２方向で対向する第２底壁を有する。一方の第１側壁７１の第１底壁とは反対側の端縁は、一方の第２側壁８２に接合される第１突出縁部Ｅ１１と、第１突出縁部Ｅ１１よりも第１底壁に近い第１ベース縁部Ｅ１２であって、一方の第２側壁８２に接合される第１ベース縁部Ｅ１２を有する。第１突出縁部Ｅ１１と第２側壁８２を接合する溶接痕ＷＰと、第１ベース縁部Ｅ１２と第２側壁８２を接合する溶接痕ＷＰは、第２方向において異なる位置に配置される。【選択図】図３
