Abstract
Abstract Two pairs of guide rails are mounted on a travelling frame of a carwashing apparatus and a truck is mounted on each pair of the guide rails for movement thereon. A supporting shaft from which a side brush is swingably suspended is rotatably supported by each truck and two cam discs are fixedly mounted on the supporting shaft for selectively actuating sensing members provided on each truck, according to the angle of inclination of the side brush, and thereby for controlling a prime mover for operating the trucks or the traveling frame.
