たことを特徴とする車両用安全車間表示装置。 A vehicle that emits display light from a display body through an optical path to a projection member in front of a driver, projects a safe distance display image of the display body onto the projection member, and forms the image within the front visual field outside the projection member. In a safe distance display device for use in vehicles, the display body is provided with a safe distance index display section for visual recognition in comparison with a vehicle traveling in front, and a direction change device that moves in the direction of the optical path,
In response to a signal from a switch means or a vehicle speed sensor, the light beam is configured such that the safe distance index is imaged in the forward field of view at a plurality of safe distances corresponding to the legal maximum speed of the expressway and a predetermined speed lower than the legal maximum speed. A safety distance display device for a vehicle, characterized in that it is provided with a direction change control means that moves the direction of a passage step by step.
