。[Scope of Claim for Utility Model Registration] A cylinder in which a heat insulating material is press-fitted near the upper edge in the axial direction corresponding to the vicinity of the piston top dead center position on the inner circumferential surface of the cylinder liner that is press-fitted to the inner wall of the cylinder. In the liner, a toughness reinforcing member made of heat-resistant steel is arranged on the inner peripheral surface of the heat insulating material to form a sliding surface of the piston, and the liner body, the heat insulating layer, and the toughness reinforcing member are arranged from the cylinder liner to the sliding surface of the piston. A cylinder liner comprising a three-layer structure of heat-resistant layers.
