To provide a new electrically-driven drive device and electrically-driven power steering device that have enhanced electrical reliability.SOLUTION: An electrically-driven drive device comprises: an electronic control unit EC for controlling an electric motor and a resin connector 13 to which an external apparatus is to be connected that are provided on an end surface part 15 of a metal motor housing 11 and a motor housing side annular groove part 35 on an outer peripheral surface of the end surface part 15 of the metal motor housing 11; and a metal cover side annular tip part 37 formed at an opening end of a metal cover 12 for covering the electronic control unit by liquid-tightly engaging with an outer periphery of the resin connector 13, the metal cover side annular tip part facing an annular groove of the motor housing side annular groove part 35. 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 40 is filled between the motor housing side annular groove part 35 and the metal cover side annular tip part 37 and a connection hole 43 for connecting the inside of the metal cover 12 and an external environment region is formed on the resin connector 13.SELECTED DRAWING: Figure 11

    【課題】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】金属製のモータハウジング11の端面部15に電動モータを制御する電子制御部ECと、外部機器を接続する樹脂製コネクタ13を設ける共に、モータハウジング11の端面部15の外周面にモータハウジング側環状溝部35を形成し、樹脂製コネクタ13の外周に液密的に係合して電子制御部を覆う金属カバー12の開口端に、モータハウジング側環状溝部35の環状溝と対向する金属カバー側環状先端部37を形成し、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40が充填されていると共に、樹脂製コネクタ13に金属カバー12の内部と外部環境域を接続する接続孔43を形成した。【選択図】図11
