PURPOSE: A power transmission device is provided to minimize the rotatory power disappearing in the transmission procedure by interconnecting a plurality of planetary units and a plurality of drums. CONSTITUTION: An external drum (200) is provided with a base framed to rotate therein. A first output shaft (300) is provided with a rotating space part through the center of one end of the external drum to rotate therein. A second output shaft (400) is provided with the rotating space part through the center of the other end of the external drum to rotate therein. A first planetary unit (600) is connected to the first input sun gear of an input shaft (500). A second planetary unit (800) is connected to the second input sun gear of the input shaft. |
