Abstract
The cover unit for a head-up display disposed in a vehicle opens and closes an opening which passes beams of an image emitted from a displaying device toward a screen. The displaying device is disposed in the dashboard, and the image is superposed on a foreground of the vehicle to be visible from a driver's eye. The screen is located outside the dashboard. The cover unit has an intercepting plate for interrupting a view line directed from the eye toward the inside of the dashboard in a standing state of the intercepting plate. The intercepting plate is movable between the standing state and a lying state. The cover unit further has a cover body movable between a closed state and an open state of the opening. The cover body is hinged to the intercepting plate so that the cover body is folded up with the intercepting plate at the open state and the cover body is extended together with the intercepting plate in the closed state. The cover body has an upper surface treated to prevent reflection of an external beam in the open state as well as in the closed state.
