内燃機関用ピストンの構造。[Claims for Utility Model Registration] In an internal combustion engine piston in which a ceramic screw and head are coaxially fitted to the top of a metal piston body, the body and the head are connected to the top of the body. By vertical engagement between a plurality of protrusions that are flush with the side wall of the head and arranged at intervals in the circumferential direction, and recesses that are spaced apart in the circumferential direction to tightly receive the protrusions on the side wall of the head. Mutual rotation around the axis is impossible, and in this meshed state,
The outer surface of the convex portion and the side wall of the head adjacent thereto form a ring-shaped group that communicates with each other over the entire circumference, and the group includes a common engagement between the main body and the blade. A structure of a piston for an internal combustion engine having a ceramic head, characterized in that the ring is fitted while retaining elasticity in the centripetal direction, thereby integrally connecting the main body and the head.
