  • FIG. 6A is an explanatory diagram schematically showing a state in which the display device is at the first position
  • FIG. 6B is an explanatory diagram schematically showing a state in which the display device is at the second position.
  • the drive unit 4 of the present embodiment rotates the display unit 2 by 180° so that the display screen 20 is on the opposite side at the first position 11, and then moves to the second position. It is configured to move up to 12.
  • the display unit 2 has a rotating shaft 23 and a rotating shaft 24 in a direction intersecting the rotating shaft 23, as shown in FIGS. 6A and 6B.
  • the rotation axis 24 is an axis for turning the display screen 20 from the user side to the windshield 83 side of the vehicle 8 .
  • the drive unit 4 of the present embodiment rotates the display screen 20 from the first position 11 so that the display screen 20 is on the opposite side, and then moves to the third position 13 by rotating the rotation shaft 23 . , and is slid into the housing 10 from the third position 13 to move the display unit 2 to the second position 12 .
  • the housing 10 is provided with an opening 104 through which the display section 2 can slide.
