PURPOSE:To miniaturize components and lighten the weight, by synchronizing an output shaft with rotational phase to heat shape memory alloy corresponding with the synchronized heating means, and by moving working members. CONSTITUTION:When a power source switch is turned ON, then heat is generated by a heater 16a because a limit switch 15a is arranged to be turned ON by an operating unit 14, and shape memory alloy 7 corresponding with the heat generation is heated to be shrunk, and a lever 7 is swung to press slide bars 13 against a rotary board 9. The surface of the rotary board 9 is arranged to be slanted to an output shaft 8, and the rotary board 9 is rotated by the pressing force of the slide bars 13 along with the rotation of the output shaft 8. The limit switch 15a is turned OFF by the rotation of the output shaft 8, and a limit switch 15b is turned ON. Accordingly, the shape memory alloy 7 is heated and shrunk by a heater 16b, and the rotary board 9 is rotated by the slide bars 13. The rotary board 9 and the output shaft 8 are continuously rotated by repeating the action. |
