The indexing positions for fixing the intermediate shafts on the carrier are set such that a tooth surface contacting state, in which one of the intermediate gears meshes with the sun gear and the internal gear, and another tooth surface contacting state, in which the other of the intermediate gears meshes with the sun gear and the internal gear, are determined to have opposite power transmitting directions.
