An impact absorber of a gears-transmission apparatus is disclosed. A gear section in the system is consisted of two rotary units, which are rotating with each other dependently. An elastic element is mounted between these two rotary units so that the mechanism is able to restore to the original position after the external torque being released. Thereby, under the condition without increasing the room available for mechanism design, the transmission apparatus possesses nice performance as a rubber belt for impact buffer from abrupt braking, instantaneous accelerating and collision . . . etc. Therefore, damage to the gear transmission system is effectively prevented so as the whole driving movement is smoother and the noise from collision of the components are also reduced.
