トン。[Claims for Utility Model Registration] 1. An internal combustion engine which has a cylindrical shape with a bottom, has a ring groove formed on its outer circumferential surface to fit an oil ring, and has an oil return passage communicating with the back surface of the ring groove. What is claimed is: 1. A piston for an internal combustion engine, characterized in that the oil return passage is constituted by a large number of through holes, and a slit is carved in the skirt portion along the axial direction. 2. The piston for an internal combustion engine according to claim 1, wherein the slit is in contact with one of the through holes. 3. A piston for an internal combustion engine according to claim 1 or 2, wherein the slit is formed at an intermediate position between the pin boss portion of the piston and the thrust direction or anti-thrust direction. 4. The piston for an internal combustion engine according to any one of claims 1 to 3, wherein an oil groove extending from the ring groove to the middle of the skirt portion is formed.
