Abstract
A balance adjusted fan mainly includes a hub, a shaft and a plurality of blades. The hub has a ring-wall and a top wall, and the shaft is connected to the top wall. The ring-wall has a plurality of socket holes that can be formed on the top edge, the bottom edge or the outside surface of the ring-wall. The blades are formed on the outside surface of the ring-wall. When the fan rotates in unbalance, at least a balance weight can be connected in one of the socket hole in an appropriate position that opposes to the heavier side of the hub to stabilize the rotation balance of the fan.
