In this planetary gear device 57, four surrounding planetary gears 61 mesh with a sun gear 59 provided at the center of the inner cylindrical roller 7 of the speed reducer 25. A ring gear 63 meshes further outside the planetary gear 61. As shown in FIG. 1, since the sun gear 59 is fixed to the inner cylinder roller 7 and the shaft 65 of the planetary gear 61 is fixed to the fixed shaft 23, the rotation direction of the sun gear 59, that is, the rotation direction of the inner cylinder roller 7 And the rotation direction of the ring gear 63, that is, the rotation direction of the outer peripheral roller 5, is the opposite direction. Less than,
The operation of this embodiment will be described.

When power is supplied to the electric motor 31 via the fixed shaft 23 and the slip ring mechanism 33, the output of the electric motor 31 is transmitted to the output shaft 27 and the fixed shaft 23 via the speed reducer 25. Since the fixed shaft 23 is fixed to the frame 9, the speed reducer 25 and the electric motor 31 rotate, and accordingly, the inner cylindrical roller 7 to which the electric motor 31 and the like are fixed rotates.

The rotation of the sun gear 59 provided on the rotating inner cylinder roller 7 causes the planetary gear 61 to rotate in the opposite direction, and at the same time causes the ring gear 63 to rotate in the opposite direction. Therefore, the outer cylinder roller 5 to which the ring gear 63 is attached
