VEHICLE DRIVE DEVICE AND PRODUCTION METHOD FOR PLANETARY GEAR MECHANISM

The numbers of teeth of all gears (36, 37) that mesh with a first gear portion (34) and a second gear portion (35) in a planetary gear mechanism (30) are values whose remainder is N when divided by 2N. 2N planetary gears (33) include N first type planetary gears (33X) and N second type planetary gears (33Y). The first type planetary gears (33X) and the second type planetary gears (33Y) are different from each other in phase of gear teeth (35a) of the second gear portion (35) with respect to gear teeth (34a) of the first gear portion (34). The first type planetary gears (33X) and the second type planetary gears (33Y) are arranged alternately in a circumferential direction.
