Abstract
An electric drive actuator opens and closes a throttle valve to control an intake air flow rate of the internal combustion engine. A motor case contains a motor constituting the electric drive actuator and a gear case contains a gear mechanism to transmit power of the motor to the throttle valve shaft. A motor inserting port of the motor case is opened to the gear case. The motor is attached to the motor case by fastening a motor bracket to screw holes with three screws. Three sides forming a contour of the motor bracket are curved lines. A motor positioning portion being fitted to the three curved lines of the motor bracket to position the motor is formed in the gear case.
