The invention discloses an anti-drag device capable of adjusting the wheel spoke hole area automatically, and relates to an anti-drag device capable of changing the hole area between spokes automatically according to the automobile speed. The anti-drag device solves the problem that the wind drag coefficient of a wheel and fuel consumption are enlarged when an automobile is driven at high speed due to the fact that air eddy is generated in a wheel cavity or positions nearby with the existence of a hole between the spokes. The anti-drag device is composed of a supporting frame, foliated cover plates and connecting transmission parts arranged between the supporting frame and the foliated cover plates, the supporting frame is fixed on a wheel hub and is located between a brake disc flange and the wheel hub, and the foliated cover plates are capable of rotating around the supporting frame. The anti-drag device does not work when the automobile speed is lower so that heat generated by frequent braking of the automobile can be emitted effectively and cannot influence the automobile. The anti-drag device is capable of decreasing the hole area between the wheel spokes automatically along with the increase of the automobile speed until the wheel hole is close to entirely closed, so that the wind drag coefficient of the automobile wheel is reduced greatly, fuel consumption is reduced, and the automobile fuel economy is improved.
