When the moving member 22 further advances in the Y1 direction from the state shown in FIG. 13 while the relative driving portion 29 is in contact with the contact support portion 4a, the rotating member 28 moves the rotating member 28 as a relative motion with respect to the forward motion. It is rotated in the direction. The pair of rotating members 28 connected by the fan-shaped gear 28b are rotated in opposite directions to each other, and the pair of supports on the moving member 22 while the moving member 22 advances from the position shown in FIGS. 13 to 14. The member 27 is moved rearward (in the Y2 direction).

While the moving member 22 advances from the position of FIG. 13 to the position of FIG. 14, the display main body 10 is further rotated in the clockwise direction (γ direction) by the switching operation of the switching unit 30. Along with this, the support member 27 retracts in the Y2 direction, so that even when the display body 10 has the tilt angle shown in FIG. 14, the regulation contact portion 15a at the tip of the regulation portion 15 is the positioning support surface of the support member 27. The display body 10 is stabilized in a tilted posture by pressing the 27a slightly strongly.

When the moving member 22 advances to the positions shown in FIGS. 15 and 16, the display body 10 further tilts in the γ direction, and the support member 27 also retracts. Then, the height position of the contact portion between the regulated contact portion 15a at the tip of the regulating portion 15 and the positioning support surface 27a of the support member 27 in the Z1 direction changes according to the tapered shape of the positioning support surface 27a. As the tilt angle of the display body 10 increases, the contact portion becomes lower. Therefore, regardless of the tilt angle of the display body 10 in the display posture, the regulation contact portion 15a at the tip of the regulation portion 15 is slightly strongly pressed against the positioning support surface 27a of the support member 27, and the display body is pressed. Each of 10 is stable in the display posture of the tilt angle.

When the display main body 10 is in the display posture of each stage of FIGS. 13 to 16 and the drive motor 25 is stopped, the posture of the display main body 10 is stabilized. Since the regulation contact portion 15a and the positioning support surface 27a are always in a slightly stronger contact with each other, the display body 10 is less likely to rattle even when vehicle body vibration or the like is transmitted to the vehicle-mounted display device 1. Further, when the display screen 12 provided on the display body 10 is provided with a translucent input panel of a resistance detection method or an electrostatic detection method, the display screen 12 is pressed with a finger to operate. Also at this time, the display body 10 does not move in the clockwise direction (γ direction) from the display posture shown in FIG.

The regulated contact portion 15a may be hard, or may be formed of an elastic body having a large Young's modulus such as hard rubber.

As shown in order from FIG. 13 to FIG. 16, when the tilt angle of the display main body 10 in the display posture in the clockwise direction gradually increases in the clockwise direction (γ direction), the display main body 10 is moved backward from the back portion 10b of the display main body 10. The protruding distances of the extending display side link portion 14 and the restricting portion 15 from the front wall portion 4 of the housing 2 gradually increase as shown by L1, L2, L3, and L4.

While the distance changes from L1, L2, L3, and L4, the display side link portion 14 and the regulation portion 15 are mainly X1 between the front wall portion 4 of the housing 2 and the back portion 10b of the display main body 10. They are only arranged side by side in the -X2 direction. Moreover, the back side surface 14b of the display side link portion 14 and the back side surface 15b of the regulation portion 15 are located on the same surface. Since the link mechanism does not extend diagonally above the back surface 14b and the back surface 15b, when the space between the front wall 4 of the housing 2 and the back surface 10b of the display body 10 is viewed, The mechanical part does not appear to be exposed, and the design can be improved.

The display main body 10 can be further stabilized at an arbitrary tilt angle between the tilt angles shown in FIGS. 13 to 16.

(Second Embodiment)
FIG. 17 shows a part of the vehicle-mounted display device 101 according to the second embodiment of the present invention. The support member 127 provided on the vehicle-mounted display device 101 is formed in a stepped shape so that the positioning support surface 127a gradually rises toward the Y2 direction, and the positioning support surface is formed at each height position. 127a is a plane parallel to the moving direction of the supporting member 127 on the moving member 22.

When the support member 127 shown in FIG. 17 is used, the display main body 10 in the display posture has four tilt angles in the clockwise direction (γ direction), and at each tilt angle, the regulated contact portion 15a Abuts on the positioning support surface 127a at each height position. At this time, even if the regulation contact portion 15a is pressed against the positioning support surface 127a relatively strongly, the component force of the pressure contact force is not directed in the Y2 direction, and the display body 10 is stable in the display posture. In this state, the phenomenon that the support member 127 is moved in the Y2 direction by the component force is unlikely to occur. Therefore, the display posture of the display body 10 can always be stabilized.
