ストン組立体。[Scope of Claim for Utility Model Registration] The piston and the small end of the connecting rod are connected by a piston pin that passes through a bearing hole provided in the diametrical direction inside the piston and a bearing hole provided in the small end of the connecting rod. A piston assembly comprising: a pressure receiving surface on the crankshaft side of the bearing hole in the small end portion and a pressure receiving surface on the combustion chamber side of the bearing hole in the piston in a projection perpendicular to the axial direction of the piston. A piston assembly characterized in that, on a surface, there are portions that overlap each other in the axial direction of the piston pin.
