PROBLEM TO BE SOLVED: To improve coupling strength between components by suppressing position deviation between the components in a fitting part, in a seat frame which is coupled by male-female fitting of the components.SOLUTION: In a bracket part 13f which is a male side of male-female fitting, a plurality of enlarged-diameter parts 13b, 13c are created along an insertion direction for the fitting. The enlarged-diameter parts 13b, 13c protrude in a direction intersecting the insertion direction. A closed cross section shape part 11B of a tower frame which is a female side of the male-female fitting is pressed from an outer peripheral side while the bracket part 13f is inserted thereinto for the fitting so as to tightly contact with the bracket part 13f along the outer peripheral surface including the enlarged-diameter parts 13b, 13c of the bracket part 13f to be coupled. |
