PROBLEM TO BE SOLVED: 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 |
