1. A throttle control apparatus having a fluid passage connecting with a combustion chamber of an internal combustion engine, the throttle control apparatus comprising:

  • a valve for communicating and blocking the fluid passage;

    a motor for generating driving force to rotate the valve in at least one of an open rotative direction and a close rotative direction;

    a plurality of gears for transmitting the driving force of the motor to the valve;

    a biasing unit for generating biasing force to bias the valve in the close rotative direction; and

    a control unit for supplying electricity to the motor to generate the driving force,wherein when the control unit terminates electricity supply to the motor, the valve is biased to a full close position by being applied with the biasing force of the biasing unit, andwhen the control unit performs a full close control to manipulate the valve toward the full close position, the control unit continues electricity supply to the motor to stop the valve at a full close control point, which is set in advance of the full close position.
