ピストン。[Claims for Utility Model Registration] (1) An upper piece made of a material with low thermal conductivity and a lower piece made of a lightweight material are connected in the axial direction of the piston pin by a fitting part formed in the axial direction of the piston pin. The upper piece and the lower piece are fitted together so that they are in contact with each other, and the contact area between the upper piece and the lower piece is reduced in the thrust and anti-thrust directions, and the upper piece and the lower piece are connected by a piston pin. Two-piece piston. (2) The two-piece piston according to claim 1, wherein the upper piece and the lower piece are separated to form a slit as a means for reducing the contact area between the upper piece and the lower piece. (3) Grooves are provided on the lower end surface of the upper piece and the upper end surface of the lower piece as a means of reducing the contact area between the upper piece and the lower piece,
A two-piece piston according to claim 1 of the utility model registration claim.
