PURPOSE: To enable a large turning effect to be obtained in an engine using many coils, by tensely providing a coil, consisting of a shape-memory alloy, between a pair of rotary units.
CONSTITUTION: A warm water tank 1 supports in a part a little upper from its liquid level horizontally rotatably a pair of rotary units on an axis. This rotary unit comprises a right rotary unit 6 and a left rotary unit 7, and the both are spirally formed by an arm and a link member 10, 16. And the both rotary units 6, 7 provide construction of line symmetry to each other. The rotary units 6, 7 placed in the symmetrical position tensely provide a coil 17aW17m between each link member 10, 16. This coil 17 is formed by shape- memory alloy. And the both rotary units 6, 7 are connected by an elastic belt 18.
