Abstract
An outdoor fan for an air-conditioner is provided to reduce unnecessary energy consumption and noise generated during an operation by reducing a side circulation flow generated when the fan rotates. The outdoor fan may include a hub shaft with a side hole, and rotary blades that convert rotary power received from the hub shaft into a pressure difference. The hub shaft may include a main plate unit perpendicular to the hub shaft and, positioned at a front side as compared to a virtual plane that includes the side hole, and the main plate unit to cover at least a portion of the hub shaft.
