A planetary gear apparatus whose gears are all constituted by continuous shifted gears. A backlash between the input sun gear and each of the input side planetary gears is adjusted by pressing a second carrier plate supporting each integrated pair of the input side planetary gears and the output side planetary gears and moving it in the axial length direction by a ball bearing by a screwing operation of an adjusting nut. A backlash between the output sun gear and each of the output side planetary gears is also adjusted by pressing the output sun gear and moving it in the axial length direction by the ball bearing by the screwing operation of the adjusting nut. Accordingly, the backlash of all meshing portions can be adjusted during or after completion of the assemblage. |
