Abstract: An adjustable sun visor has an elongated clamp body formed from a resilient material and having an oval tubular shape dimensioned for frictional engagement around a vehicle roof pillar. A pair of sun shields are pivotally mounted on the clamp body through a plurality of axially spaced rings. The sun shields may be formed from a plurality of extensible sections slidably connected by cooperating dovetail projections and recesses. Spaced apertures on the sun shields receiving the rings secured to the clamp body may each be provided with a resilient bushing for frictional engagement with the respective mounting ring. Each of the bushings has a circumferential undercut groove which engages a cylindrical side wall surrounding an aperture in the sun shield. Each bushing has a central bore having a diameter which flares outwardly in opposite axial directions from a minimum diameter at a midpoint of the central longitudinal axis of the bushing.
