PROBLEM TO BE SOLVED: To prevent the occurrence of an unwashed part on a car body surface by controlling a travel driving means and a moving means on the basis of a detecting signal of a relative position detecting means so as to perform brushing washing on the car body surface of a rear part more than the brushing washing-performed car body surface by moving a washing brush to a washing position. SOLUTION: After rotating rocker brushes 11, 11 by being moved to a closed position, a traveling frame 1 is moved forward. When the traveling frame 1 moves forward by a prescribed distance, side brushes 10, 10 so far existing in an opening position are moved up to a washing position running along a side surface of an automobile V, and brushing washing is performed up to a rear end part of the automobile V by a top brush 9, the side brushes 10, 10 and the rocker brushes 11, 11. Thus, since brushing washing is performed on a car body side surface corresponding to the brushes 10, 10 by the side brushes 10, 10 at backward moving time of the traveling frame 1 while moving the traveling frame 1 forward by putting the side brushes 10, 10 in an opening position, an unwashed part can be prevented. |
