Vehicle sun shield assembly

Abstract

A sun shield assembly includes a case having a mandrel received therein and a fabric is wrapped around the mandrel. The case is fixed on a top of a vehicle by first suction members and the fabric is connected to a pull rod which has second suction members. The fabric can be pulled out from the case and fixed to the body of the vehicle to cover the vehicle so that the vehicle is not directly exposed under the sun. A separation member has a slit through which the fabric extends so as to define a gap between the body of the fabric and the fabric.
