A vehicle display device that has a projecting unit configured to output projection light and also has a directional mirror configured to reflect the projection light and to direct reflected light (L4, L5) of the projection light upward at an oblique angle toward a transparent screen positioned in front of a driver seat, the vehicle display device further comprising: a tilting fulcrum part positioned between an upper end of the directional mirror and a lower end of the directional mirror, the tilting fulcrum part being attached to the directional mirror; a fulcrum support configured to support the tilting fulcrum part; a biasing member configured to give the directional mirror a biasing force with which the tilting fulcrum part is pressed against the fulcrum support; an abutting surface positioned above the fulcrum support so as to face an upper portion of a back of the directional mirror, the back being opposite to a reflecting surface of the directional mirror; and a driving unit configured to perform an adjustment operation in which the driving unit gives the lower end of the directional mirror a force so that the directional mirror is tilted around the tilting fulcrum part between a clockwise rotation limit orientation (a) and a counterclockwise rotation limit orientation (β) in a state in which the tilting fulcrum part is supported by the fulcrum support; and in a state in which the rotational angle of the directional mirror has exceeded the counterclockwise rotation limit orientation (β) the driving unit is configured to perform a retracting operation in which the driving unit gives the lower end of the directional mirror a force directed to a forward in a reflection direction so that the upper portion of the back of the directional mirror above the tilting fulcrum part comes into contact with the abutting surface and the directional mirror is rotated around the point of contact acting as a fulcrum in a state in which the tilting fulcrum part is apart from the fulcrum support. a tilting fulcrum part positioned between an upper end of the directional mirror and a lower end of the directional mirror, the tilting fulcrum part being attached to the directional mirror; a fulcrum support configured to support the tilting fulcrum part; a biasing member configured to give the directional mirror a biasing force with which the tilting fulcrum part is pressed against the fulcrum support; an abutting surface positioned above the fulcrum support so as to face an upper portion of a back of the directional mirror, the back being opposite to a reflecting surface of the directional mirror; and a driving unit configured to perform an adjustment operation in which the driving unit gives the lower end of the directional mirror a force so that the directional mirror is tilted around the tilting fulcrum part between a clockwise rotation limit orientation (a) and a counterclockwise rotation limit orientation (β) in a state in which the tilting fulcrum part is supported by the fulcrum support; and in a state in which the rotational angle of the directional mirror has exceeded the counterclockwise rotation limit orientation (β) the driving unit is configured to perform a retracting operation in which the driving unit gives the lower end of the directional mirror a force directed to a forward in a reflection direction so that the upper portion of the back of the directional mirror above the tilting fulcrum part comes into contact with the abutting surface and the directional mirror is rotated around the point of contact acting as a fulcrum in a state in which the tilting fulcrum part is apart from the fulcrum support.
