To provide a new electrically-driven drive device and electrically-driven power steering device that have enhanced mechanical and electrical reliability.SOLUTION: An electrically-driven drive device comprises: a motor housing side annular groove part 35 formed on an outer peripheral surface of an end surface part 15 of a metal motor housing 11 on an opposite side to an output part of a revolving shaft 23 of an electric motor, the motor housing side annular groove part being composed of an annular groove retreating inside in the radial direction orthogonal to an axial line of the motor housing 11; and a metal cover side annular tip part 37 formed at an opening end of a metal cover 12 for covering an electronic control unit for controlling the electric motor, the metal cover side annular tip part facing the annular groove of the motor housing side annular groove part 35 from outside. In a state in which the metal cover side annular tip part 37 is disposed so as to face the motor housing side annular groove part 35, a liquid seal agent is filled between the motor housing side annular groove part 35 and the metal cover side annular tip part 37 and an annular inclined surface inclined and expanded outwardly in the radial direction of the metal cover is formed on an inner peripheral surface of the metal cover side annular tip part 37.SELECTED DRAWING: Figure 11

    【課題】機械的及び電気的な信頼性を高めた新規な電動駆動装置及び電動パワーステアリング装置を提供する。【解決手段】電動モータの回転軸23の出力部とは反対側の金属製のモータハウジング11の端面部15の外周面に形成され、モータハウジング11の軸線に直交する径方向の内側に後退する環状溝からなるモータハウジング側環状溝部35と、電動モータを制御する電子制御部を覆う金属カバー12の開口端に形成され、モータハウジング側環状溝部35の環状溝に外側から対向する金属カバー側環状先端部37とを備え、モータハウジング側環状溝部35に金属カバー側環状先端部37が対向して配置された状態で、モータハウジング側環状溝部35と金属カバー側環状先端部37との間に液状シール剤が充填されていると共に、金属カバー側環状先端部37の内周面には、金属カバーの径方向で外側に向けて傾斜して拡開する環状傾斜面が形成されている。【選択図】図11
