The invention concerns a sun visor for an automotive vehicle, or the like, which is adapted to safety requirements. The visor body has a frame that is flush with the outer surface of the sun visor body. The sun visor has a mirror in the visor body that is protected by a cover. The cover is swivelably mounted to the visor body frame to swivel between its open and closed conditions. A separately swivelable control knob selectively locks closed and permits opening of the cover. The control knob has a recess for capturing the free edge of the cover and swiveling of the control knob with the edge of the cover in the recess locks the cover closed. A detent locks the knob in the open condition. The cover is an integral unit including a pin that is received in a hole in the frame for supporting the cover, the swiveling cover itself and a hinge between the attached and swiveling portions of the cover.
