Abstract
An indication display unit for vehicles of this invention is provided with a head-up display (HUD), an indication projector, a display device located at the ceiling of the vehicle, and a reflector forwardly located relative to a driver's seat. The indication display unit of this invention further includes a shifting mechanism for the reflector so that when the vehicle speed decreases lower than a predetermined low speed limit, the reflector can be completely shifted away from the driver's visual field. The shifting of the reflector can be accomplished by having the reflector shift in a vertical direction or just outside, but near the driver's visual field, in a horizontal direction.
