PURPOSE: A vibration reducing device for a handle of a ground compacting device is provided to improve durability of a ground compacting device and safety of a user by reducing excessive vibration generated from the handle of the ground compacting device. CONSTITUTION: A vibration reducing device for a handle of a ground compacting device comprises a bracket(13), an auxiliary bracket(14), a hinge bar(22), a rubber bushing(21a,21b,21c), and a metal bushing(19). The bracket is fixed to an upper plate(25) and comprises an upper divergence plate(15a) and a lower divergence plate(16a). The auxiliary bracket is symmetrically fixed corresponding to the bracket and comprises an upper divergence plate(15b) of the auxiliary bracket and a lower divergence plate(16b) of the auxiliary bracket. The hinge bar is formed on an end of a handle(12) and is inserted into a fixed shaft(17a) between the upper divergence plate of the bracket and the lower divergence plate of the bracket. The rubber bushings are fixed to each fixed shaft. The metal bushings are mounted on the surface of the rubber bushing in order to protect the rubber bushing.
