Abstract

An automotive electrically-powered steering device is provided which is easy of assembly and electric connections. The steering device includes an electric motor, a motor torque transmission mechanism, a torque detector, and a motor controller which are arranged integrally as a unit. The controller includes a motor driver and a control substrate to which terminals of the motor driver are connected electrically. A steering shaft passes through a portion of the control substrate. The electrical terminals of the motor, the torque detector, and the motor driver extend in an axial direction of the steering shaft and connect electrically to the control substrate from the same side.
