An electrical sunshade assembly includes a tubular mounting unit adapted to be secured in an automobile adjacent to a window of the latter and formed with a longitudinally extending slot. A pinion is disposed rotatably in the mounting unit and is driven to rotate in opposite first and second directions. Two racks are disposed movably in the mounting unit on two sides of the pinion. Each rack meshes with the pinion and has a connecting end portion. Rotation of the pinion in the first direction causes the connecting end portions of the racks to move away from each other, while rotation of the pinion in the second direction causes the connecting end portions to move toward each other. A screen unit is located adjacent to the slot of the mounting unit and includes a sun screen and an axially rotatable roller which is biased to wind the sun screen normally thereon. Each of two linking rods has a first end portion connected pivotally to the sun screen and a second end portion connected pivotally to the connecting end portion of a respective one of the racks such that movement of the connecting end portions of the racks away from each other causes unwinding of the sun screen from the roller to shield the window and such that movement of the connecting end portions toward each other causes winding of the screen on the roller.
