PURPOSE:To convert the low temperature thermal energy into the dynamic energy easily by coupling facing crank sections of two crank shafts having the symmetric crank sections through a basic operation mechanism comprising shape memory alloy elements. CONSTITUTION:The crank shafts 20, 30 having plural crank sections 21-24 and 31-34 shifted respectively by 90 deg. are born rotatably in parallel with interval and respective shafts 20, 30 are set such that the facing crank sections 21-24, 31-34 will be symmetrical with respect to a plane XX'-YY'. Respective shafts 20, 30 are rotated in the opposite directions by gearing the gears 62, 63 provided at respective shaft ends through the gears 64, 65. Then the facing crank sections 21-24, 31-34 are coupled through helical shape memory alloy coils 11-14 and a temperature difference between the upper and lower faces of a plane VV'-WW' passing through the center lines of respective shafts 20, 30, is set thus producing the power.
