摘要： To achieve an integration of components and the rationalization of the default opening mechanism of the throttle valve, a reduction of the load of the motor drive and a stabilization of the throttle control operation. In a default opening setting mechanism with which the default opening of the throttle valve 24 is maintained to be larger than the fully closed position when the electric current does not pass through the motor 12 driving the throttle shaft 18, the throttle lever 3 and the sleeve 45 are inserted and fixed, and the sleeve 42 united together with the return lever 2 is engaged with the sleeve 45 so as to be enabled to rotate in relative to the sleeve 45. The sleeve 42 is energized by the return coil in the close direction of the throttle valve 24 up to the initial opening position. This energized operation enables the return lever 2 to be coupled with the sleeve 3. A force for opening the valve for keeping the default opening the throttle valve 24 is energized by the spring 5 onto the throttle shaft 18 near the fully closed position.

摘要： In a throttle body there are provided a throttle valve for controlling the flow of intake air in an internal combustion engine, and an electrically-driven actuator for actuating the throttle valve. A cover, which covers a receptacle portion, is attached to a side wall of the throttle body. The throttle assembly of the invention is provided with a potentiometer type sensor for detecting the degree of opening of the throttle valve, the sensor comprising a slider and a resistor, the slider being adapted to slide on the resistor and mounted to a peripheral surface of a driven gear so that a tip end thereof faces in a radial direction of a throttle valve shaft. The resistor is constituted by a curved resistor which confronts the slider in the said radial direction. A wall portion which holds the curved resistor is formed by molding integrally with the aforesaid cover.

摘要： A returning spring of the electronic control throttle and a default spring for securing an initial opening degree (default opening degree) of the throttle valve have diameters different from each other, and both of the springs are held around a shaft of the throttle valve shaft and arranged between a gear attached to the throttle valve shaft and a wall portion of the throttle body. A shaft supporting gap of the throttle valve shaft is filled with an air leak preventing material, and a minimum opening degree for control of the throttle valve is set to a value larger than an amount of overshoot of the throttle valve occurring when opening degree of the throttle valve is changed from a maximum opening degree on control purpose of the throttle valve to the minimum opening degree.

摘要： 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.
