A flap drive for a flap includes two identical lever joint arrangements which are arranged in pairs at a distance from one another. The flap can be moved out of its closing position into its opening position and back by the flap drive. In this case, the lever joint arrangements are articulated pivotably with one of their ends in each case on a side region of the flap and with their other ends at a fixed location on the motor vehicle. The mutually corresponding pivot axes of the articulation points extend coaxially to one another. Movement transmission devices for the pivotable drive of a driven lever of each lever joint arrangement are guided by a common motive drive unit, the driven levers being articulated at a fixed location on the motor vehicle.
