Abstract
An airflow generating apparatus is provided. Fan blades are disposed around a hub, and one side of a fan blade is partially fixed on the peripheral of the hub, and another portion not fixed on the peripheral side of the hub is a free portion swinging with airflow. Therefore, the airflow generating apparatus employing the fan blades can adjust the swaying angle in accordance with the variation of different flow fields, so as to maintain a smooth airflow.
