The original instructions in "The Karakurizui", recommends using whalebones for springs, including the spiral spring. However, in this new model, steel is used instead. Its mechanism transforms the power of the spring winding down into the doll's movement. Power is derived as the spring goes winding down. As the spiral spring gradually winds down, the driving wheel turns with the first gear via the second gear in mesh. This is how it moves.
