Stirling engine

A Stirling engine comprising:

• a cylinder;
• a piston reciprocatably disposed inside the cylinder;
• a displacer that reciprocates with a phase difference relative to the piston;
• a linear motor that drives the piston;
• and
• a pressure vessel that encloses the cylinder, the piston, and the linear motor,
• wherein the linear motor has, at both ends thereof, synthetic resin end brackets, and wherein the pressure vessel has a division portion formed therein, the division portion being located in a central portion of the linear motor along an axis thereof.
