A transmission system of eyebrow-beautifying device is disclosed. A lever member has two contacts at bottoms of both sides. The contacts rest on a periphery of a wear-resistant member. A pivot point of a transmission unit and the lever member is disposed above the contacts. A torque of the lever member is substantially the same as that of the transmission unit. A rate of wear between the lever member and the wear-resistant member is substantially the same as that between the transmission unit and the lever member. That is, no amplification of error or wear may exist therebetween. Hence, the prior drawback of deterioration of vibration of the motor shaft caused by serious wear of the action block is completely eliminated.
