Claims

[Scope of utility model registration request]

In a dissimilar material joint with a cylindrical structure, which is constructed by joining a cylinder made of a metal material and a cylinder made of a CFRP laminated material in the direction of the axis of both cylinders, a part protrudes from the metal material side into the CFRP laminated material almost parallel to the cylinder axis. A dissimilar material joint having a cylindrical structure, characterized in that the protruding end is provided with a protrusion whose wall thickness increases in a direction substantially perpendicular to the protrusion direction.
