Patent ID: 8807117

Claim:
A throttle valve device comprising: a throttle body which has an intake path; a motor which is mounted in the throttle body; an output gear which is fastened to a rotor shaft of the motor; a throttle shaft which rotates in the intake path; a final stage gear which is fastened to the throttle shaft; a rotor which is fastened to the throttle shaft; an intermediate gear which meshes with the output gear and the final stage gear; a throttle valve which is fastened to the throttle shaft; a gear cover which covers the output gear, the final stage gear and the intermediate gear and is made by resin; a retainer which is positioned on the gear cover to prevent the axial separation of the intermediate gear; a connector which is mounted on the gear cover; a plurality of connector terminals mounted on the connector; a circuit board which is mounted on the gear cover; a sensor circuit which is mounted on the circuit board and positioned to face the intermediate gear; a detector that detects the rotational position of the throttle shaft, the detector which is provided on the circuit board and positioned to face the rotor; and a plurality of sensor connection conductor sections which are disposed along one side of the circuit board to connect the connector terminals to the sensor circuit, wherein the sensor connection conductor sections are insert-molded into the gear cover and are disposed on both sides of the retainer.
