<P>PROBLEM TO BE SOLVED: To provide a driving mechanism capable of accumulating a large energy compared with a conventional driving mechanism and preventing abrasion and fracture by reducing the height and friction of a main spring. <P>SOLUTION: The driving mechanism includes: a body part 2 disposed on a shaft 3 so as to rotate about a rotation axis 4 of the shaft part 3; and a main spring unit configured to include a first spring 8 and a second spring 11 that are coaxially disposed while being vertically superposed in the body part 2. The first spring 8 is connected to the body part 2 at one end thereof, and the second spring 11 is connected to the shaft part 3 at one end thereof. A plate 14 is rotatably disposed about the rotation axis 4, and the other end of the first spring 8 is connected to the center part and the other end of the second spring 11 is connected to the periphery of the plate 14 such that the both springs 8 and 11 are simultaneously wound around the rotation axis 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
