<p>The present invention relates to an electronic throttle assembly and, more specifically, to an electronic throttle assembly which allows a valve plate to stably be opened and closed by preventing a shaft of the valve plate from being moved inside a valve housing due to a force applied to the axial direction of the rotational axis. To achieve the above, the electronic throttle assembly controls the amount of opening of the valve plate equipped in an intake port by a driving motor, and forms a receiving groove wherein a segment gear transmitting power of the driving motor to the valve plate is mounted. The present invention comprises: an insertion hole formed through the center of the receiving groove; a bearing inserted and mounted in the insertion hole; the shaft crossing the intake port by being inserted through the center of the bearing, equipped with the valve plate in an external surface thereof; and a fixating means penetrated by the shaft inside the insertion hole, preventing a movement of the shaft toward the rotational axis.</p> |
