Claims

[Claims for Utility Model Registration] 1. A connector for an internal combustion engine that has a big end that is pivotally connected to a crankshaft at one end, a small end that is connected to a piston at the other end, and has an oil supply groove formed on the side surface of the big end. A connecting rod for an internal combustion engine, characterized in that the oil supply groove is set at an arbitrary angle with respect to an axis connecting the centers of a big end and a small end. 2. The connecting rod for an internal combustion engine according to claim 1, wherein the oil supply groove is provided at a position rearward of the axis with respect to the rotational direction of the crank pin. 3. The connecting rod for an internal combustion engine according to claim 1, wherein the oil supply groove is formed of a plurality of grooves set in different directions. 4. The connecting rod for an internal combustion engine according to claim 1, wherein the oil supply groove is provided only on one side of the big end.
