To provide a gas lubrication structure for a Stirling engine that achieves satisfactory static pressure gas lubrication in executing gas lubrication.
In the gas structure, the Stirling engine 10A includes: a hot temperature side cylinder 20 including a hot- temperature side cylinder 22 and an expansion piston 21; a pair of cylinders composed of a low temperature side 30A including a low temperature cylinder 32 and a compression piston 31A; and a crankcase 120A. The expansion piston 21 includes: a first accumulator R1, a first air-feed hole S1 spewing a working fluid into a clearance formed between the first accumulator R1 and the hot temperature side cylinder 22; and a check valve 40 that introduces the working fluid into the first accumulator R1 from an inside of the crank case 120A.
