ELECTRONIC CONTROL APPARATUS

摘要

An electronic control apparatus includes an electric motor including a rotor and a stator; a circuit board configured to drivingly control the electric motor; and a housing unit accommodating the electric motor and the circuit board. A vehicle-body attaching portion of the housing unit is attached and fixed to a vehicle body. The vehicle-body attaching portion is located on one side of the rotor with respect to an extending direction of the rotor. At least one of both surfaces of the circuit board is a component-mounting surface. The circuit board is fixed to the housing unit in a state where the both surface of the circuit board extend along the rotor of the electric motor. A large-size electronic component is mounted on a vehicle-body-attaching-portion-side portion of a peripheral portion of the component-mounting surface which is close to the vehicle-body attaching portion.
