Abstract

PURPOSE: A connecting rod for a vehicle is provided to improve the durability of a piston and a piston ring by cooling the inner wall of the piston through the installation of a filter bed and a screen with a case. CONSTITUTION: A groove(22) is formed in the upper end of a small end portion(20) having an oil supply hole(12), and a filter bed and a screen are attached onto the groove. A case having many oil outlet holes is mounted onto the groove. The oil outlet holes are inclined to the shaft of a connecting rod(10). The oil flowing out through the oil outlet holes is evenly injected into the filter bed. Thus, the filtering effect of the oil is maximized. The oil supplied to the groove through the oil supply hole is evenly injected through the oil outlet holes in various angles. The oil filtrated via the filter bed and the screen is evenly injected into an inner wall(54) of a piston. Therefore, the inner wall of the piston is cooled.
