ABSTRACT:
There is disclosed a planet gear apparatus having a gear structure wherein a sun gear attached to an input shaft is a conical involute external gear, one of two adjacent ring gears differing slightly in inside diameter and number of teeth is a stationary ring gear fixed to the planet gear apparatus, the other of the two ring gears is a rotary ring gear rotating about an rotational axis of the input shaft, and a plurality of planetary gears are cylindrical involute spur gears. A rotational axis of each planetary gear is inclined at an angle to the rotational axis of the input shaft, and each planetary gear is meshed between the sun gear, on the one hand, and the two ring gears, on the other, while rotating about its own axis and revolving around the sun gear.
