Abstract
In the developed state of the combiner 13, the first arm 19 extends along a vertical line passing the center of gravity G of the combiner 13, and the second arm 21 and the third arm 23 are aligned on and extended along a line which couples the rear end of the base member 17 and the other end 19b of the first arm 19 and tilts from the vertical direction toward the horizontal direction so that the combiner 13 is arranged in front of the eye point I at a tilting angle of reflecting the image light of the displayed image emitted from the display device of the projector unit 9 toward the eye point I of the driver 3. In such a configuration, the virtual image of the displayed image on the combiner which is to be visually recognized from the eye point can be visually recognized stable with no shaking in a vehicle which is susceptible to the vibration from the road face.
