Claims

[Scope of utility model registration request]

The connecting body and the connecting rod cap are fastened together in a plane perpendicular to the axial direction of the crankshaft on at least one of the connecting rod body joint surface and the cap joint surface of the joint part where the connecting rod body and the connecting rod cap are joined. A joint structure of a connecting rod, characterized in that a concave portion is formed, the apex being at a point on the axis of a bolt hole of a bolt, and becoming shallower as the distance from the apex increases.
