The main shaft is fixed upward. A rotating plate 4 is rotatably mounted on the main shaft 2 via a bearing 3. A plurality of planetary gear shafts 5 are provided concentrically on the rotating plate 4, and a bearing 6 is interposed between the rotating plate 4 and the planetary gear shafts. 7 is a planetary gear fixed to the planetary gear shaft 5. A center gear 8 is integrally fixed to the main shaft 2, and the center gear 8 and the planetary gear 7 are meshed with each other. Reference numeral 9 denotes a drive lever provided on the planetary gear shaft 5 via a one-way clutch 10. The planetary gear 7 can be rotated by rotating the drive lever 9 in one direction. When rotated in the opposite direction, the one-way clutch 10 does not transmit rotational force to the planetary gear 7.

A cylindrical body 13 that slidably holds the is fixed. A stopper 14 is fixed to the tip of the connecting shaft 11 passing through the cylinder 13.
A shape memory alloy coil 15 is placed between the cylindrical body 13 and the cylindrical body 13.
is provided. When this coil 15 is immersed in hot water, it expands and causes the connecting shaft 11 to protrude outward against the spring 16. Further, when the coil 15 is removed from the hot water, it is air-cooled and contracted as the connecting shaft 11 sinks inward due to the force of the spring 16.

て回転板４も逆方向に回転しない。上記動作が繰
り返されて回転板４は一方向に回転を続ける。 First, when the coil 15 is immersed in hot water, it expands into a memorized shape. This expansion of the coil 15 causes the connecting shaft 11 to protrude outward and rotate the drive lever 9 in the direction of the arrow. This rotation of the drive lever 9 is transmitted to the planetary gear shaft 5 via the one-way clutch 10 and rotates the planetary gear 7. As the planetary gear 7 rotates, it revolves around the center gear 8 with which it is meshed. As the planetary gear 7 revolves, the planetary gear shaft 5 also revolves, and the rotating plate 4 is rotated. This rotation of the rotary plate 4 is output as power energy. Due to the rotation of the rotary plate 4, the immersed coil 15 comes out of the hot water, and when it is air cooled, the force of the spring 16 becomes larger, and the connecting shaft 1
1 inward, and the coil 15 contracts. At this time, the drive lever 9 rotates in the opposite direction, but the one-way clutch 10 prevents the planetary gear shaft 5 from rotating, and the planetary gear 7 does not rotate in the opposite direction. Therefore, the rotating plate 4 also does not rotate in the opposite direction. The above operation is repeated and the rotary plate 4 continues to rotate in one direction.
以上の説明から明らかなように、本発明によれ
