PURPOSE:To form each diameter into the same and aim at the promotion of lightweightiness and miniaturization as a whole by increasing two sets of transmission spur gears to a dual differential gear. CONSTITUTION:Intermediate gears 9 and 12 on a planetary carrier 2 are used for part of an interlocking gear of a worm in a dual differential gear 1, and this planetary carrier 2 is rotated by a main shaft 17 via a planetary carrier disc 18, whereby each interlocking gear will do in the same diameter as a known toe center differential gear, thus an outer diameter of the planetary carrier 2 is in no case increased at all.
