PURPOSE: An automatic car wash of heavy vehicle includes a brush moving in slope method and a side mirror escaping instrument, thereby preventing the fracture of a side mirror and washing efficiently the front surface and the roof of a vehicle in a short time. CONSTITUTION: An automatic car wash of heavy vehicle includes numerous frames mounted in the structure of lattice to support numerous brushes and numerous rotatable brushes. The automatic car wash of heavy vehicle comprises a slope frame(300), an actuating source, a chain(304), and an actuating body(310). The slope frame(300) is set upwards on a frame in the vehicle moving direction, to wash the front surface and the roof of a heavy vehicle. The actuating source, a motor, includes a pair of sprockets(306) on the slope frame(300). The chain(304) engages with the sprocket and is positioned in the form of an endless track along the slope frame(300). The actuating body(310) hangs a brush(160) and moves upward and downward along the slope frame(300) by the chain(304). At one side of the actuating body(310) is mounted the side mirror escaping instrument which assumes the digital "C" type.
