Abstract

PURPOSE: To obtain optinum output according to the temperature of heat source by supporting slidably the bearing of pulley to rotatably support a shape-memory alloy by a shape-memory alloy provided inside a hot water tank and a spring.
CONSTITUTION: A coiled shape-memory alloy 16 is laid with tension between pulleys 8, 9, 11, and 15, the shape-memory alloy 16 between the pulleys 8 and 11 is dipped in cold water inside a cold water tank 1A, and the shape-memory alloy 16 between the pulleys 9 and 15 is dipped in hot water inside a hot water tank 1B. Also, the bearing 13 of the pulley 15 is supported slidably by a shape-memory alloy element 21 provided inside the hot water tank 1B and a spring 17. Thus, since the amounts of strain and stress on the shape-memory alloy element 21 can be altered by changing the temperature of heat source, optimum output according to the temperature of the heat source can be obtained.
