Abstract
In a case of performing a static pressure gas lubrication by a stirling engine provided with a pair of cylinders of a high-temperature-side cylinder 20 and a low-temperature-side cylinder 30, a stirling engine gas lubrication structure is provided with an introduction pipe 70A for introducing a working fluid existing within a low-temperature working space into at least an inside of an expansion piston 21 of the expansion piston 21 and a compression piston 31, the low-temperature working space being included in a working space where the working fluid circulates between the cylinders 20 and 30, a temperature of the working fluid in the low-temperature working space lower than that of the working fluid in a working space of a high-temperature side cylinder 22 in a driving state.
