PURPOSE:To protect a car and the captioned apparatus from being damaged by operating the apparatus by electrically detecting contact of a side brush with the car to be washed and allowing the side brush to wash the whole side surface from the center front to the rear edge and allowing a protruded article to perceive the brush pressure and take a round. CONSTITUTION:A side brush 45 contacts with the front part of the car to be washed, and the pushing force pushes a guide arm 14 and moves the detecting piece 20 positioned on the free edge side of the arm 14, and an approach switch 21 at the rear area of a supporting frame 15 is operated, and advance of the body is stopped. At the same time, air is supplied into an air cylinder 35, and a piston rod 36 is fastened. A swing arm 26 turns around a longitudinal pivot shaft 29, and the side brush 45 is oriented washes the front grille and the bumper of the car towards the outer side. For the protruded part 58 etc., the guide arm 14 retreats temporarily and the brush pressure can be softened. The impact on Return of the brush to the center is absorbed by a shock absorber 43. Thus, the car and the apparatus can be protected from being damaged. |
