PROBLEM TO BE SOLVED: To provide a sterling engine with two displacers provided for one piston, which has less fear of breakage and is easy to control and inexpensive. SOLUTION: The sterling engine 1 has a cylinder 11L with the displacer 13L inserted therein and a cylinder 11R with the displacer 13R inserted therein, which are arranged on opposite sides of a cylinder 10 with a piston 12 inserted therein. The displacers 13L, 13R are fixed to opposite ends of a shaft 14. The displacer 13L is connected to a heat-transfer head 31L through a spring 40 for generating resonance. When the piston 12 is reciprocated by a linear actuator 20, the displacers 13L, 13R also reciprocates, and working gas moves between a compression space 34L and an expansion space 35L and between a compression space 34R and an expansion space 35R. This causes heat-transfer heads 30L, 30R to be heated and the heat-transfer heads 31L, 31R to be cooled. COPYRIGHT: (C)2005,JPO&NCIPI
