関用ピストン。[Scope of Claim for Utility Model Registration] (1) In a piston for an internal combustion engine in which a cooling cavity is provided on the outer periphery of a combustion chamber of the piston, the wall thickness of the wall surface between the contact surface of the piston and the cooling cavity is determined by the contact surface of the piston. A piston for an internal combustion engine, characterized in that the piston is formed thicker than the wall thickness of the wall between the fire surface and a wall other than the cooling cavity. (2) Practical use characterized in that the wall thickness between the contact surface of the piston and the cooling cavity is formed to be at least twice the wall thickness of the wall surface between the contact surface of the piston and an area other than the cooling cavity. A piston for an internal combustion engine according to claim 1 of the patent registration claim.
