PROBLEM TO BE SOLVED: To provide a brushless motor including a motor housing which is lightweight, can also be easily manufactured and attains compaction while also including ECU attachment, an electrically-driven power steering device with the same mounted therein, and a vehicle.SOLUTION: The brushless motor includes the motor housing in an integrated structure including a motor attachment flange at one end side of a motor yoke and including an ECU attachment flange at another end side. Inside of the motor housing, a ring for linear expansion coefficient compensation that is formed by insert casting is provided, and the ring includes a notch in an axial end portion. A circumferential width of the notch becomes narrower toward the axial end portion.SELECTED DRAWING: Figure 4
【課題】軽量で製造も容易であり、ECUの取付けも含めてコンパクト化を図ったモータハウジングを備えたブラシレスモータ並びにそれを搭載した電動パワーステアリング装置及び車両を提供する。【解決手段】モータヨークの一端側にモータ取付けフランジが設けられ、他端側にECU取付けフランジが設けられた一体構造のモータハウジングを備え、モータハウジングの内側に、インサート鋳造で形成された線膨張率補償用のリングを設けており、リングは軸方向端部に切欠きを有し、切欠きは、軸方向端部に向かって周方向幅が狭くなっている構成とするブラシレスモータである。【選択図】図4
