A printing material containing a white layer and an absorption layer formed on a base material made of a resin film. There is provided a swivel-adjustable luggage compartment cover which is pivoted to the motor vehicle in its front end region and is positively coupled to the tailgate by coupling elements in its rear end region, so that opening of the tailgate causes the luggage compartment cover arranged below it to be opened. A dampening fluid is filled within the indicator case as well, and acts to reduce the possibility of misalignment by reducing wobble of the angle indicator as a ship wheel is rotated.
