Abstract
Abstract Car conveyor, in particular one intended for a car washing machine, which moves the car with the aid of stops pushing against the wheels on one side at least and which consists of an elastic tube flattening under the car wheel to full closure, into which tube a liquid or gaseous pressure medium is conducted so that the stop moving the car wheel is formed of the inflating tube. The tube has been composed of hollow wedge-like parts, which have been placed one into the other and joined at their outer rims so that within the tube chambers are formed, and that at the narrower end of the wedge-shaped part there is an aperture for conducting the pressure medium from one chamber to the other.
