To provide a drive device capable of improving abrasion resistance and strength of a gear close to an output shaft on a drive transmission system path.SOLUTION: In a drive device that rotates the same output shaft 2 by two motors 9A, 9B, two planetary type planetary gear mechanisms are configured so that an external gear 5 and a carrier 2 are shared, and planetary gears 3A, 3B and sun gears 4A and 4B are dedicated, and drive is respectively transmitted from the two motors 9A, 9B to the sun gears 4A, 4B. The drive device has control means 11 that performs control capable of reducing backlash by the two motors 9A, 9B. A brake that can be switched between an operation state and a non-operation state may be provided in each of drive transmission paths to the planetary gears 3A, 3B respectively corresponding to the motors 9A, 9B.SELECTED DRAWING: Figure 1 【課題】駆動伝達系路上で出力軸に近い歯車の耐摩耗や強度を向上させることができる駆動装置を提供する。【解決手段】２つのモータ９Ａ，９Ｂによって同一の出力軸２を回転させる駆動装置において、外歯車５とキャリア２とは共用になるとともに、遊星歯車３Ａ，３Ｂと太陽歯車４Ａ，４Ｂとは専用になるよう２つのプラネタリ型遊星歯車機構を構成し、各太陽歯車４Ａ，４Ｂに２つのモータＡ，９Ｂから駆動を伝えるようにした。２つのモータ９Ａ，９Ｂによりバックラッシ低減可能な制御を行う制御手段１１を有する。各モータ９Ａ，９Ｂに対応する遊星歯車３Ａ，３Ｂまでの駆動伝達経路内それぞれに、作動・不作動切り替え可能なブレーキを設けてもよい。【選択図】図１
