Abstract
A frame body (1) includes a first surface (11), a second surface (12), and two side surfaces (13). Each of the side surfaces (13) has a single bent part or two or more bent parts (14). The first surface (11) and an outer part (13a) of each of the side surfaces (13) form an angle of approximately 90 degrees or larger than 90 degrees inside the closed cross-section in the cross-section of the frame body (1). At least one of the side surfaces (13) includes a low-strength part (17) closer to the second surface (12) and a high-strength part (18) closer to the first surface (11), and includes a strength transition part (19) located closer to the second surface (12) than a specific bent part (the bent part (14) which is closest to the second surface (12) and protrudes inward of a closed cross-section).
