PURPOSE: A brush structure for an automatic vehicle washing device is provided to reduce the shock transferred to a vehicle, to effectively remove a foreign matter and to enhance the vehicle washing function by making contact with the outer surface of the vehicle using a high-speed rotor of a spiral shape. CONSTITUTION: A brush structure for an automatic vehicle washing device comprises a frame(100), a body(200) and a sponge cleaning member(300). The frame is connected to a driving unit to make an axis-rotation and comprises one more openings(110), which are formed as a groove shape along the length. The body is inserted into the outer circumferential surface of the frame. One or more protrusions(210), which are protruded to be inserted into the opening of the frame, are formed on the inner side of the body. Semispherical inserting units(220), which are cut to the outer circumferential surface at the given position of the upper surface of the body, forms a diagonal-shape groove to the given position of the lower part and are circular-arranged on the outer circumferential surface at regular intervals. |
