ABSTRACT:
An indication display unit for a vehicle, includes a reflecting device having a reflecting surface directed to a driver's seat which reflecting surface has a reduced reflectivity. An indicating device having an indicating surface directed to the reflecting surface of the reflecting device. Operational information concerning driving operation of the vehicle is indicated on the indicating surface of the indicating device, and is reflected on the reflecting surface of the reflecting device to be visibly observed by a driver. As the reflectivity of the reflecting surface is reduced, the visibility of the displayed image from the indicating surface may be improved. Since the reflecting device is provided on a dashboard, and the indicating device is located at any position other than the dashboard, a meter hood may be removed to ensure more space in the dashboard. The reflecting device is composed of a reflecting plate and a frame for supporting the reflecting plate, which is preliminary curved with a relatively good accuracy. In constructing the reflector, the reflecting plate is cured by forcibly following the curvature of the frame, thereby easily obtaining a curvature of the reflecting plate with a relatively good accuracy.
