A slip control device including a shaft fixed to a reference surface; a first gear rotatably coupled to the shaft by a predetermined friction force with respect to an external circumferential surface of the shaft, for slipping with respect to the shaft when applied a rotation force greater than the predetermined friction force; a friction unit configured to provide the predetermined friction force between the first gear and the shaft; a rotation gear box for covering at least one surface of the first gear, coupled to a second gear to be rotated around the external circumferential surface of the shaft, and for rotating about the shaft during rotation of the second gear; and a motor disposed in the rotation gear box and providing the second gear with a rotation force to rotate the rotation gear box about the first gear. |
