A seat frame for a framework structure of a vehicle seat includes a plurality of frame bodies formed by bending a single tubular member. The single tubular member is formed in a closed cross-sectional shape by a single long and flat member being bent in a direction that is at a right angle with respect to the lengthwise direction of the long and flat member, and then end edges of the tubular member that have come to face each other being joined together by welding. Each of the plurality of frame bodies includes a bend part and rectilinear parts. The bend part is rectangular in cross section. The rectilinear parts include a rectangular cross section portion and a cross-section-varying portion. The end part of the cross-section-varying portion, connected to the rectangular cross section portion, is rectangular in cross section.
