A swing type fan including a frame, a motor, at least one blade, at least one first magnetic element and at least one second magnetic element is provided. The motor is fixed to the frame and has a shaft passing through the frame. The blade is disposed between the shaft and the frame and has a first side and a second side opposite to the first side. The first side of the blade is connected to the frame. The first magnetic element is disposed on the blade and is located between the first side and the second side of the blade. The second magnetic element is connected to the shaft and is corresponding to the first magnetic element. The second side of the blade swings via a magnetic force between the first magnetic element and the second magnetic element as the shaft drives the second magnetic element to rotate.
