Abuts the part. At this time, the restricting contact portion 15 a is slightly in pressure contact with the positioning support surface 27 a of the support member 27 by the operation timing of the drive unit 20 of the switching drive mechanism 8 and the operation timing of the switching unit 30.

  During the time when the moving member 22 advances to the position shown in FIG. 13 at the latest, the relative driving part 29 extending downward from the pivoting member 28 on the moving member 22 is in the Y2 direction of the front wall 4 of the housing 2 The facing inner surface hits the abutment support 4a. When the moving member 22 is further advanced in the Y1 direction from the state of FIG. 13 while the relative driving portion 29 abuts on the abutting support portion 4a, the pivoting member 28 shown in FIG. It is pivoted in the direction. The pair of pivoting members 28 connected by the sector gear 28b are pivoted in the opposite direction to each other, and while the moving member 22 advances to the position of FIGS. The member 27 is moved rearward (in the Y2 direction).

  While the moving member 22 advances to the position of FIG. 13 to FIG. 14, the display body 10 is further rotated clockwise (γ direction) by the switching operation of the switching unit 30. Since the support member 27 retreats in the Y2 direction along with this, the restricting contact portion 15a at the tip of the restricting portion 15 is the positioning support surface of the support member 27 even when the display main body 10 is at the falling angle shown in FIG. The display main body 10 is stabilized in the fallen posture by being pressed against the surface 27a slightly more strongly.

  Also when the moving member 22 advances to the positions of FIGS. 15 and 16, the display main body 10 further falls in the γ direction, and the support member 27 also retracts. Then, the height position in the Z1 direction of the contact portion between the control contact portion 15a of the tip of the control portion 15 and the positioning support surface 27a of the support member 27 changes in accordance with the tapered shape of the positioning support surface 27a. As the tilt angle of the display main body 10 becomes larger, the contact portion becomes lower. Therefore, the control contact portion 15a at the tip of the control portion 15 is slightly pressed against the positioning support surface 27a of the support member 27 regardless of which step the display main body 10 falls in the display attitude, and the display main body 10 is stabilized at the display attitude of the fall angle respectively.

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

  The regulation 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 moves rearward from the back surface portion 10 b. The protruding distances of the extending display side link portion 14 and the restricting portion 15 from the front wall 4 of the housing 2 gradually become longer as indicated by L1, L2, L3, and L4.

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

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

Second Embodiment
FIG. 17 shows a part of the in-vehicle display device 101 according to the second embodiment of the present invention. The support member 127 provided in the in-vehicle display device 101 is formed in a step shape so that the positioning support surface 127a gradually becomes higher as it goes in the Y2 direction, and the positioning support surface is provided at each height position. A plane 127 a is parallel to the moving direction of the support member 127 on the moving member 22.

  When the support member 127 shown in FIG. 17 is used, the display main body 10 serving as the display attitude has four inclination angles in the clockwise direction (γ direction), and the regulation abutment portion 15a at each inclination angle Is in contact with the positioning support surface 127a at each height position. At this time, even if the restricting contact portion 15a is relatively strongly pressed against the positioning support surface 127a, the component of the pressing force is not directed in the Y2 direction, and the display main body 10 is stable in the display attitude. In the state, the phenomenon that the support member 127 is moved in the Y2 direction by the component force hardly occurs. Therefore, the display attitude of the display main body 10 can always be stabilized.
