装置。It has a piston that reciprocates within the cylinder by a piston rod, and a housing that is fixed within the cylinder in a manner facing the piston and that defines a compression chamber whose volume is variable between the piston and the piston. and a Stirling, wherein the back pressure chamber in the housing and the compression section chamber are sealed by a shaft sealing device that is in sliding contact with the piston rod, and the compression section chamber constitutes a part of a closed circuit for working fluid. In the engine, the shaft sealing device includes a piston ring made of synthetic resin and having a slit on the side surface facing the compression section space, and at least a part of the abutment of the piston ring and arranged on the outer peripheral surface of the piston ring. A shaft sealing device for a Stirling cycle engine, characterized in that the shaft sealing device has a bank seal ring that closes the compression chamber, and the slit allows a flow of working fluid from the back pressure chamber to the compression chamber.
