ON-VEHICLE DISPLAY UNIT

In the on-vehicle display unit 5, an indicated image on an indication surface 51a of the display 51 is reflected by a semi-transparent mirror 55 to be directed above a dashboard 1 through a window 59b formed in a cover plate 59a disposed on an upper surface 1a of the dashboard 1. Thereby, the image is projected on a windscreen 3. The semi-transparent mirror 55 is moved in a longitudinal direction of the vehicle, so that the vertical position of a projection point P1 or P3 of the image S1 or S3 on the windscreen 3 is changed such that the image is superimposed over the foreground at which a driver of the vehicle is looking. The cover plate 59a is supported by a cover support construction 59c so as to be movable in a longitudinal direction of the vehicle relative to the upper surface 1a of the dashboard 1.
