したことを特徴とする内燃機関のピストン。The piston head is formed separately from the piston body using a highly heat-resistant material with low thermal conductivity, and a cylindrical ring is attached to the outer periphery of the boss that protrudes integrally from the center of one side of the piston head. In addition to providing clearance fit, a retaining pin is provided that passes through the boss and the cylindrical ring in a direction substantially perpendicular to the axis of the piston, and the cylindrical ring of the boss is cast into the piston body along with the retaining pin. A piston for an internal combustion engine characterized by an integrated piston head.
