を特徴とするピストン。(1) The piston crown is made of a material different from the piston body, and the lower surface of the piston crown has a hanging portion extending downward and a bulge extending outward in the radial direction of the piston from the hanging portion at a distance from the lower surface of the piston crown. The piston body is inserted between the protruding part of the rib and the lower surface of the piston crown, and the piston crown cannot be removed by the engagement between the protruding part and the protruding part. In a piston that is cast into a piston body, the upper surface of the bulging portion of the rib and the lower surface of the intrusion portion of the piston body are arranged in a radial direction of the piston from the center of the reference surface when the lower surface of the piston crown is the reference surface. It is characterized by forming a taper that coincides with a straight line extending outward and downward, and in which the upper surface of the bulging portion and the lower surface of the intrusion, and the lower surface of the piston crown and the upper surface of the piston body are brought into sliding contact with each other. piston.
