PROBLEM TO BE SOLVED: To provide a joint body, a seat frame for automobile and a joining method capable of joining a tabular member and a pipe-like member firmly and capable of reducing weight.SOLUTION: A joint body includes: a thin plate in which a plurality of through-holes are formed along an outer periphery; a first member having a base part in which one part comes into contact with the thin plate, and a protrusion part protruding with respect to a contact surface coming into contact with the thin plate of the base part and inserted in the through-hole; and a second member arranged on the opposite side from the base part via the thin plate, and made of the same material as the first member. The thin plate is made of a material whose specific gravity is smaller than that of the materials constituting the first member and the second member. The second member and an end part of the protrusion part on the opposite side from the side connected to the base part are connected by one part of them being melted and solidified respectively.SELECTED DRAWING: Figure 3
【課題】板状の部材とパイプ状の部材とを強固に接合することができ、かつ軽量化することができる接合体、自動車用シートフレームおよび接合方法を提供すること。【解決手段】外周に沿って複数の貫通孔が形成される薄板と、一部が薄板に接する基部と、基部の薄板と接する接触面に対して突出し、貫通孔に挿通されている突出部とを有する第1部材と、薄板を介して基部と反対側に配置され、第1部材と同じ材料からなる第2部材と、を備え、薄板は、第1部材および第2部材を構成する材料よりも比重の小さい材料からなり、第2部材と、突出部の基部に連なる側と反対側の端部とは、各々の一部が溶融固化して連なっている。【選択図】図3
