Abstract: A sun visor includes a flat sun visor body which is moved between its use position over the windshield and its non-use position above the windshield by being slid between those positions along a guide rail, and without being swiveled around a bearing. A bearing bracket which projects above and rearwardly of the rear surface of the visor body terminates in a guide from which a plurality of guide pins project laterally. The guide pins are received in guide grooves of rails disposed between the ceiling of the passenger compartment and the roof of the vehicle. The pins move along the rails and guide the sun visor body so that its leading or front edge moves down over the windshield, while its trailing or rear edge moves forward along the ceiling of the vehicle. There are two pairs of the pins which project from opposite surfaces of the guide. At least one of the pairs of pins is positioned in a common borehole and are spring biased apart.
