燃機関のピストン。An annular cooling chamber is formed on the lower side of the piston top wall, and the lower surface of the lower wall portion of the cooling chamber between the pair of piston pin holes is formed in a plane orthogonal to the piston center line. A pair of ribs are formed for each mounting seat to serve as a chamber cover mounting seat, extending from both ends of the mounting seat to the screw pin boss, and the ribs are sloped downward toward the outer circumference of the piston to connect the ribs and the mounting seat. A piston for an internal combustion engine, characterized in that the angle between the rib and the mounting seat is obtuse, and the radius of the joint between the rib and the mounting seat is increased.
