Claims

[Scope of utility model registration request]

In a connecting rod formed by joining together a plurality of press-molded connecting rod constituent plates each having an annular protrusion forming a small end shaft hole and an annular protrusion forming a large end shaft hole, A connecting rod characterized in that at least one of the connecting rod constituent plates is provided with a projection, and the plurality of connecting rod constituent plates are integrally joined by fixing the protrusion to another connecting rod constituent plate.
