To provide a driving force assisting unit configured in a relatively small-size and capable of transmitting large torque without loss and a power-assisted device with the driving force assisting unit.SOLUTION: A driving force assisting unit 10 is a driving force assisting unit configured to assist man-power driving, which is applied by a user to a power input shaft 11, with a motor 12 and to take out power from a power output shaft to the outside. Also, the driving force assisting unit 10 is connected to the power input shaft 11 or the power output shaft in a driving manner, and includes a first clutch 14 formed with a clutch surface facing toward the axial direction of the power input shaft 11, a second clutch 15, and a third clutch 16. Further, the driving force assisting unit includes a spring 67, a spring 66, and a bearing 64 as clutch support means supporting the first clutch 14, the second clutch 15, and the third clutch 16 from the axial direction.SELECTED DRAWING: Figure 4

    【課題】比較的小型であり、且つ、大きなトルクを損失無く伝達することができる駆動補助ユニットおよびそれを備えた電動アシスト装置を提供する。【解決手段】駆動補助ユニット10は、使用者が動力入力軸11に与える人力駆動をモータ12で補助し、動力出力軸から動力を外部に取り出す駆動補助ユニットである。また、駆動補助ユニット10は、動力入力軸11または動力出力軸と駆動的に接続され、動力入力軸11の軸方向を向くクラッチ面が形成された第1クラッチ14、第2クラッチ15および第3クラッチ16を有する。更に、第1クラッチ14、第2クラッチ15および第3クラッチ16を軸方向側方から支持するクラッチ支持手段として、スプリング67、スプリング66およびベアリング64を有する。【選択図】図4
