Abstract
A Stirling engine including a crosshead mechanism includes a low-pressure space and a high-pressure space. In the high-pressure space, a piston is driven by a heating/cooling cycle of a working fluid. The low-pressure space accommodates a crosshead portion connected to the piston via a piston rod, and a crank mechanism that rotates a crankshaft along with movement of the crosshead portion. A high-pressure gas seal in which a lip angle of a seal lip on the high-pressure side is smaller than that on the low-pressure side is provided around the piston rod at a partition between the low-pressure space and the high-pressure space.
