。In a non-lubricated piston in which a gas inlet opening on the top surface of the piston and a gas outlet opening on the outer circumferential surface of the piston are connected to each other by a gas flow passage formed inside the piston, there is a gap between the gas outlet and the top surface of the piston. A non-lubricated piston, which is located in a piston, and has a ring groove formed on the outer circumferential surface of the piston near the top surface of the piston, and a piston ring inserted into the ring groove.
