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 2 includes: a first conductive housing 3; a second conductive housing 4; and an elastic body 7. The first conductive housing 3 includes: a first frame part 33 which encloses a housing part 36 configured to house a circuit board for controlling driving of an electric motor; an edge part 33t of an outer periphery of an end surface of the first frame part 33; and a guide part 34 in which part of a surface located at the inner side of the edge part 33t protrudes. The second conductive housing 4 includes: a top plate part 41 covering one surface side of the housing part 36; a second frame part 42 of the top plate part 41 which may be fitted in the outer periphery side of the guide part 34; and claw parts 43 in which part of the second frame part 42 protrudes to the opposite side of the top plate part 41. The elastic body 7 is disposed on the edge part 33t between the first frame part 33 and the second frame part 42. The claw parts 43 are electrically connected with the first housing 3.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2は、導電性の第1筐体3と、導電性の第2筐体4と、弾性体7とを含む。導電性の第1筐体3は、電動モータの駆動を制御する回路基板を収納する収納部36を囲む第1枠部33と、第1枠部33の端面の外周の縁部33tと、縁部33tの内側の一部の表面が突出する案内部34と、を含む。導電性の第2筐体4は、収納部36の一面側を覆う天板部41と、案内部34の外周側に嵌め合わせ可能な天板部41の第2枠部42と、第2枠部42の一部が天板部41の反対側に突出する爪部43とを有する。弾性体7は、第1枠部33と第2枠部42との間で、縁部33tに介在する。爪部43は、第1筐体3に電気的に接続している。【選択図】図5
