Pin holes 40, 40 (one side is not shown) for rotatably connecting are formed at corresponding portions thereof.

As shown in FIGS. 4 and 5, a second closing spring 27 is attached to the connecting pin 25, so that the second hood 23 closes the opening 13 like the first hood 22. It is always urged in the closing direction.

The urging forces of the first and second closing springs 26 and 27 of the first hood 22 and the second hood 23 are large in the first closing spring 26 and small in the second closing spring 27. Is set as follows. With such a relationship, the first hood 22 and the second hood 23
Is always closed, and in this closed state,
At the connecting portion between the second hood 23 and the first hood 22, that is, at the connecting pin 25, the hoods 22 and 23 do not bend. As a result, the first hood 22 and the second hood 23 have substantially the same planar shape, and the appearance is improved.

With respect to such a hood 17, the display 9 stands up so that the pin 20 slides up in the cam groove 21. At the time of this rising, the back surface 9a of the display 9 comes into contact with the back surface of the hood 17 and pushes up the hood 17, so that the hood 17 opens.
Open 3.

The display 9 and the hood 17 are brought into contact with each other in a slidable state. In order to perform this sliding, the back surface 9a of the display 9 is
A rotor 29 is attached to the tip of the
Back surfaces 22a and 23 of the first hood 22 and the second hood 23
Ribs 30 and 31 are formed in the a at positions facing the rotor 29, respectively.

As shown in FIG. 6, the rib 30 on the side of the first hood 22 is formed at a substantially central portion in the width direction at the end on the side of the second hood 23, and the rib 3 on the side of the second hood 23 is formed.
As shown in FIG. 7, 1 is formed so that the hood 23 is longitudinally cut in a substantially central portion in the width direction.

In this structure, when the display 9 stands up, the rotor 29 contacts the rib 31 of the second hood 23, and the rotor 29 rolls along the rib 31 and the display 9 tilts upward. Then, by further tilting the display 9 upward, the rotor 29 is set to the first position.
The first hood 22 is pushed up while coming into contact with the rib 30 of the hood 22 and rolling along the rib 30. This allows
The first hood 22 is pushed up against the biasing force of the first closing spring 26 and rotates upward, so that the entire hood 17 is separated from the opening 13 and the opening 13 is opened.

The rotor 29 and ribs 30 and 31 as described above
In the sliding by, the friction between the display 9 and the hood 17 is reduced, so that the smooth operation can be performed. Further, since the contact area between the rotor 29 and the ribs 30 and 31 is small, when the display 9 is raised or stored,
No abnormal noise is generated.

By the above operation, the display 9 can be projected from the opening 13 and put into a use state as shown in FIG. In the upright state of the display 9, the second hood 23 is bent from the first hood 22 toward the display 9 by the urging force of the second closing spring 27, so that the display 9 is covered. As a result, even when sunlight enters the vehicle from the front wind panel, the liquid crystal panel 10 of the display 9 does not reflect, and the liquid crystal panel 10 of the display 9 is easy to see.

In this actual configuration, the second hood 23 in a state where the hood 17 is upright has the driver's eye point at the last sliding position (rearmost) of the seat (not shown) as shown in FIGS. 5 and 8. 32 and display 9
It is set so as to be located between the tangent line 35 and the eye point 32 with respect to the upper limit of and the tangent line 34 with the front hood 33 (FIG. 8) of the vehicle body.

This means that the second hood 23, that is, the display 9, is located below the lower limit of the forward field of view seen by the driver during driving, and the display 9 does not obstruct the forward field of view. The field of view can be secured.

As a result, even if the display 9 is arranged on the upper surface of the instrument panel 1, the display 9 does not hinder driving.

The second hood 23 is substantially entirely above the tangent line 35 connecting the eyepoint 32 and the upper limit of the display 9. Therefore, the second hood 23 does not get in the way when the display 9 is viewed, and the display 9
Is easier to see.

As shown in FIGS. 4 and 5, a sheet-shaped heat insulating material 28 is attached to the back surface of the hood 17. Although the heat insulating material 28 is arranged on the back surface of the first hood 22, it is attached to the first hood 22 at a plurality of positions, and similarly on the back surface of the second hood 23. It is attached at an appropriate place.

As the heat insulating material 28, one having an air layer is preferable, and for example, urethane foam, polypropylene, polyethylene mixed non-woven fabric or the like can be selected.

Thus, the heat insulating material 2 is provided on the back surface of the hood 17.
By providing 8, the amount of heat transferred to the inside of the case 8 is reduced even if the temperature of the hood 17 rises due to sunlight, so the display 9 in the case 8 can be protected from heat.

The display 9 is stored in the case 8 in a prone state. That is, the display 9 is stored so that the liquid crystal panel 10 faces the bottom surface 8 a of the case 8. For the display 9 in this prone state,
Ventilation holes 16 facing the liquid crystal panel 10 are formed on the bottom surface 8a of the case 8 as shown in FIGS. 4 and 5. In addition to this, a conduction hole 15 is formed in the mounting recess 14 formed on the upper surface of the instrument panel 1.
As shown in FIG. 4, the conduction hole 15 and the ventilation hole 16 communicate with each other.

As described above, the communication hole 15 and the ventilation hole 16 communicate with each other, so that the in-vehicle air A can be introduced into the ventilation hole 16 from the insertion hole 15.

Then, the introduced air in the vehicle comes into contact with the liquid crystal panel 10 of the display 9 to cool the liquid crystal panel 10.

Therefore, even if the instrument panel 1 becomes high in temperature due to the radiant heat of sunlight, the liquid crystal panel 10
Therefore, the temperature rise is reduced, and the liquid crystal panel 10 is not thermally destroyed.

This eliminates the inconvenience caused by the high temperature when the display 9 is placed on the upper surface of the instrument panel 1.

FIG. 9 is a diagram in which the locus of movement of the display 9 is continuously drawn. By setting the shape of the cam groove 21 that guides the movement of the display 9, FIG.
It moves according to a trajectory like. In the movement along such a locus, the movement from the prone state to the standing state is smoothly performed, and thereby the good standing can be performed.
