An electric fan is provided to rotate a fan blade to blow a wind in every direction without driving a motor, selectively restrain a wind blowing direction and supply a wind at a required position by adjusting the height of a support of the electric fan. An electric fan for supplying a wind in every direction includes a fan stand(1), a vertically movable support(2) fixed to the stand with a fixing member(3), a motor(4) placed at the top of the support, a case(4a), and blades(5b) arranged at a predetermined interval around a top plate(5a) and attached to a motor shaft(4b). A connecting plate(5c) is connected to the bottoms of the blades. An air inlet(5e) is formed between a rotation axis(5d) and the blades.
