PROBLEM TO BE SOLVED: To provide a head-up display device that hardly causes distortion to a virtual image to be displayed even when an angle of a combiner is changed.SOLUTION: A head-up display device 1 is mounted to a vehicle instrumental panel to display vehicle information, navigation information, or the like, and comprises: an irradiation device 2 that performs irradiation with display light; a semi-transmissive combiner 3 that displays a virtual image (each information mentioned in the above) by reflecting the display light; rotation displacement means 4 that is provided on a lower end side of a combiner 3 and performs an angle adjustment by performing a rotation displacement of the combiner 3; and a housing 9 that houses the irradiation device 2 and the rotation displacement means 4. A rotation center axis P of the combiner 3 is set on a reflection surface 30a of the combiner 3, and a movement trajectory N of a lower end of the combiner 3 represents an arc centering around the rotation center axis P. |
