PROBLEM TO BE SOLVED: To provide an electric power steering device which secures electromagnetic shield property of a control board for controlling driving of an electric motor and reduces vibrations of a second housing serving as a cover, and to provide an electronic control unit.SOLUTION: An electric control unit includes: a first conductive housing including a first frame part which encloses a housing part configured to house a circuit board for controlling driving of an electric motor, an edge part of an outer periphery of an end surface of the first frame part, and a guide part in which part of a surface located at the inner side of the edge part protrudes; a second conductive housing including a top plate part covering one surface side of the housing part, a second frame part of the top plate part which may be fitted in the outer periphery side of the guide part, and claw parts in which part of the second frame part protrudes to the opposite side of the top plate part; and a resin covering an inner side surface and an end surface of the second frame part and disposed on the edge part. Each claw part is exposed from the resin to be electrically connected with the first housing.SELECTED DRAWING: Figure 5

    【課題】電動モータの駆動を制御する制御基板の電磁シールド性を確保しつつ、カバーとなる第2筐体の振動を低減する、電動パワーステアリング装置及び電子制御ユニットを提供する。【解決手段】電子制御ユニットは、電動モータの駆動を制御する制御基板を収納する収納部を囲む第1枠部と、第1枠部の端面の外周の縁部と、縁部の内側の一部の表面が突出する案内部と、を含む導電性の第1筐体と、収納部の一面側を覆う天板部と、案内部の外周側に嵌め合わせ可能な天板部の第2枠部と、第2枠部の一部が天板部の反対側に突出する爪部とを有する、導電性の第2筐体と、第2枠部の内側面及び端面を覆い、縁部に介在する樹脂と、を備える。爪部は、樹脂から露出して第1筐体に電気的に接続している。【選択図】図5
