PURPOSE: A driver of an electric sheet of a vehicle for preventing power loss is provided to prevent the generation of mechanical noise by applying driving current of forward and reverse direction against a driving motor by using a transistor. CONSTITUTION: A driver of an electric sheet of a vehicle for preventing power loss includes a current conversion circuit, an instruction switches, an IC(140) and a cutoff transistor. The drive motor transfers the sheet in a forward and reverse direction. The current conversion circuit applies driving current in forward and reverse direction of the driving motor. The current-switch circuit comprises a plurality of transistors. The IC generates operation signal according to on/off of the instruction switch.
