Abstract
In an electric power steering device in which a control unit and a motor are integrated, when the control unit is housed in a case, although a frame, by which the motor and the control unit are compartmentalized, is required, there have been problems in that the case is deformed by a pressure which influences the case when the frame is provided, and a position accuracy of a shaft center of a rotation shaft of the motor is worsened. Therefore, in order to reduce a deformation of the case, a step portion is provided at an inner wall surface of the case and the frame is contacted to the step portion, and moreover, a connecting portion is provided between an outer circumference portion of the frame and an inner circumference portion of the case, whereby a movement of the frame is restrained.
