Abstract
The present invention provides a drive gear device that can easily be made compact and lightweight with a simple configuration, and that has little friction loss. Among externally toothed sun gear members () and ring gear members () of first and second planetary gear mechanisms (), one pair, which are first paired members (), are coupled to a coupling member () for equalizing the rotational speeds and rotational directions of the first paired members (), and the other pair, which are second paired members () are coupled to opposite rotation members () for making the second paired members () rotate in opposite directions. Rotational torque inputted to the coupling member () is distributed to the first planetary gear mechanism () and the second planetary gear mechanism (), and is outputted from planetary carriers ().
