Abstract
Mechanical properties, in particular torsional rigidity and absorbed energy properties in axial crushing, of a joint structure body including a joint formed by joining members are further improved.Provided is a first member, a second member, an end of the second member being thrust against a surface of the first member, and a joint that joins the first member and the second member are included. The joint includes an end flange that is formed continuously along the end of the second member and of which at least one part overlaps the surface of the first member and a unit joint that joins the end flange and the first member. The end flange is formed continuously to at least one part of the end of the second member via a rising curved surface portion and the rising curved surface portion includes a wall-thickened portion of which a sheet thickness is made larger than a sheet thickness of the second member. At least one part of the unit joint is provided in a range of 3 mm or less from a boundary between the end flange and the wall-thickened portion.
