To provide an electric driving device and power steering device capable of enhancing mechanical and electrical reliability while miniaturizing appearance shape to reduce the weight.SOLUTION: An electric driving device and power steering device includes: a motor housing-side annular groove part 35 constituted of annular grooves retreating to the inside in the radial direction orthogonal to an axis of a motor housing 11; a metal cover-side annular tip part 37 formed on an opening end of a metal cover 12 which covers an electronic control part to oppose to the motor housing-side annular groove part 35 from outside; wherein a liquid-sealing agent 41 is filled between the motor housing-side annular groove part 35 and the metal cover-side annular tip part 37, and wherein a cross-sectional shape in the axial direction of the motor housing-side annular groove part 35 is formed in such a shape in which a tensile force applied on the liquid-sealing agent 41 along a push-in direction of the metal cover-side annular tip part 37 is reduced.SELECTED DRAWING: Figure 11
【課題】機械的及び電気的な信頼性を高めると共に、外観形状を小さくして重量を低減する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ことにある。【解決手段】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の溝からなるモータハウジング側環状溝部35と、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の環状の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と金属カバー側環状先端部37との間に液状シール剤41が充填されていると共に、モータハウジング側環状溝部35の軸方向に沿った断面形状が、金属カバー側環状先端部37の押し込み方向に沿って液状シール剤41が引っ張られる引っ張り力を低減する形状に形成されている。【選択図】図11
