To provide a driving unit which can transmit power to a driving object quickly even if failure occurs in a driving device or a power source which is mainly used, and to provide an electric power steering device.SOLUTION: A driving unit 10 includes a main driving device, an auxiliary driving device, a speed reducer 13, and a connection device 15. The main driving device has a first output shaft 11a which receives energy of a main driving source to rotate. The auxiliary driving device has a second output shaft 12a which receives energy of the main driving source or an auxiliary driving source to rotate. The speed reducer 13 has: an input shaft 16 connected with the first output shaft 11a; and an output rotating body 17 which outputs rotation having reduced speed to the outside. The connection device 15 connects the second output shaft 12a of the auxiliary driving device with the input shaft 16 or the first output shaft 11a when failure occurs in the main driving device.SELECTED DRAWING: Figure 2

    【課題】主となる駆動装置や電源に故障が生じた場合にも、駆動対象に速やかに動力を伝達することができる駆動ユニット、及び、電動パワーステアリング装置を提供する。【解決手段】駆動ユニット10は、主駆動装置と、補助駆動装置と、減速機13と、接続装置15と、を備えている。主駆動装置は、主駆動源のエネルギーを受けて回転する第1出力軸11aを有する。補助駆動装置は、主駆動源、または、補助駆動源のエネルギーを受けて回転する第2出力軸12aを有する。減速機13は、第1出力軸11aが連結される入力軸16、及び、減速された回転を外部に出力する出力回転体17を有する。接続装置15は、主駆動装置が故障したときに、補助駆動装置の第2出力軸12aを入力軸16または第1出力軸11aに接続する。【選択図】図2
