る鉄道車両用のヘツドアツプデイスプレイ。[Claims for Utility Model Registration] An information projector comprising an optical information display means having a display surface on which information is displayed, and an optical member that projects information display light emitted from the display surface in a predetermined direction. and is installed at an angle in front of the pilot, and transmits light rays from the outside world from the front to the rear so that the pilot can visually recognize the scene of the outside world in front of the driver, and also transmits information projected from the information projecting device. In a head-up display for a railway vehicle that is equipped with a windshield having a combiner function that reflects display light in a direction visible to the operator, the reflective surface of the windshield that reflects the information display light is arranged in the vertical and horizontal directions. and the optical member has a cylindrical optical member that compensates for the difference in optical power in the longitudinal direction and the lateral direction of the windshield reflective surface, and the cylindrical optical member is configured to have different optical powers. A head-up display for a railway vehicle, characterized by being arranged so that its position can be adjusted around its optical axis.
