Abstract
The numbers of teeth of all gears that mesh with a first gear portion and a second gear portion in a planetary gear mechanism are values whose remainder is N when divided by 2N. 2N planetary gears include N first type planetary gears and N second type planetary gears. The first type planetary gears and the second type planetary gears are different from each other in phase of gear teeth of the second gear portion with respect to gear teeth of the first gear portion. The first type planetary gears and the second type planetary gears are arranged alternately in a circumferential direction.
