A driving body acceleration device using elasticity includes an input gear, a carrier connected to the input gear, planetary gears mounted to the carrier such that each of the planetary gears is rotated about a hinge shaft, a sun gear threadedly engaged with the planetary gears while being surrounded by the planetary gears, an output shaft coupled to the center of the sun gear, a cam having a cam groove, and acceleration units, each of which has one end coupled to a corresponding one of the hinge shafts and the other end coupled to the cam groove, and each of which rotates a corresponding one of the hinge shafts such that each of the planetary gears is rotated, when the revolution angle at one end of each of the acceleration units is different from that at the other end of each of the acceleration units. |
