Abstract

The element joint is obtained by joining: a long pipe; a short pipe made of a quality of material having a strength equal to or higher than a strength of the long pipe; and a plate material made of a quality of material having a strength equal to or higher than a strength of the short pipe. In the element joint, at least one member of the long pipe and the short pipe includes a pipe-shaped portion, and the pipe-shaped portion of the one member is pipe-expanded and joined to the other member by press-fitting. The short pipe and the plate material are welded to each other.
