Abstract: A route indicator for use in automobiles and other motor vehicles uses a route instruction card of a flexible material maintained in a coaxial position within a transparent hollow cylinder by hoop tension produced by the natural elasticity of the card. One end of the cylinder is fastenable by an interference fit to a cup-shaped cap rotatably fastened to the upright portion of a bracket fastenable to a structural member within the vehicle. The cylinder is readily removable from the cap to permit replacement of an instruction card through an open end of the transparent cylinder.
