  • the image is displayed as a virtual image so as to be visible from the occupant 6 in the moving body.
  • the projection main body 25 has a projection area 27, and both reflection surfaces 21 and 22 for reflecting a display light image projected on the projection area and displaying a virtual image are formed in a curved surface shape.
  • the fastening protrusion protrudes from the projection main body, and forms a flat fastening surface 29b that comes into surface contact with the seat surface as the fastening protrusion 26 fastened to the base by the inserted fastening member.
  • the head-up display device 1 described above includes the combiner 20 that is fastened to the base 4 in the moving body 2 by the fastening member 30 that forms the planar seating surface 32a, and displays from the projection unit 10 to the combiner.

  • the projection main body of the combiner is formed in a curved surface with both reflection surfaces for reflecting the display light image projected on the projection area and displaying a virtual image. Therefore, in the combiners disclosed in the first and second disclosures, the fastening protrusions protruding from the projection main body and fastened to the base in the moving body by the fastening members form a flat fastening surface that comes into surface contact with the seating surface. According to this, the fastening projection receiving the fastening stress at the planar fastening surface that is in surface contact with the planar seating surface of the fastening member is not easily distorted, but also on the projection main body from which the fastening projection is projected. Is difficult to propagate such fastening stress. Therefore, distortion can be prevented from occurring in the projection body where the projection area is set, so that it is possible to ensure clear visibility of the display light image that is reflected on both reflection surfaces in the projection area and displayed as a virtual image. It becomes.
