・54 is forcibly pressed against the edge of the tilt up guide 51c ・52c, so there is no risk of it shaking.

Next, in order to change from the tilt-up state to the fully open state, the second
The moving shoe 49 of is moved backward.

As a result, the first and second engaging bodies 53 and 54 are connected to the guide groove 5.
1 and 52 fully closed guide parts 51b and 52b, and the first
The fully open state shown in the figure is obtained. In this case, by providing an upwardly projecting circular arc portion 52d in the area of the fully open guide portion 52b, the rear seal member 11 once moves further downward from the fully open position (solid line in Figure 1) and returns to the fully open position again. . Thereby, the sealing member 11 comes into proper elastic contact with the roof opening edge 1a without being deformed.

On the other hand, the cable 87 is driven from the fully open state shown in FIG.
When the moving shoe 49 is further moved rearward to approach the third moving shoe 55, the first and second engaging bodies 53 and 5
4 moves from the fully open guide portions 51b and 52b to the tilt down guide portions 51a and 52a. At this time, the second engaging body 54 moves upward and rotates the lifting arm 47 counterclockwise using the first engaging body 53 as a fulcrum.
A tilt-down state is obtained in which the rear end side is lower than the outer panel 5. At this time, the operating lever 29 is pressed by the lid 9, and the head of the stopper bottle 27 is pressed by the biasing spring 37.
Press against. As a result, the stopper bin 27 is removed from the opening 39, and the restraint of the first moving shoe 19a is released. On the other hand, during a series of operations of the lid 9, the second moving shoe 49 and the locking part 57 press the restraining member 75 of the third moving shoe 55 against the biasing spring 73, and the locking part 57
and the engaging body 67 are integrally coupled. When the cable 87 is further driven in the same direction from this state, the second and third moving shoes 49 and 55, the lid 9, etc. move together into the rear roof space W, and the roof opening lower opens wide. An open state is obtained.

The lid 9 in the stored state can be pulled out to the fully open position by performing the operation opposite to the above. Note that the biasing member 56 does not necessarily need to be provided on the bottom surface 50, and the biasing member 56 protruding inward can be provided on the first and second guide bodies 59.
It may be provided on the 60 side. In this case, a protrusion for riding on the biasing member 56 projecting inward is provided on the lifting arm 47 side.

The biasing member 56 in this embodiment is formed of a band-like spring material, and both ends 56b are connected to the lower side 47a of the lifting arm 47.
By being incorporated into the engagement recesses 91, 91 provided in the above, the action portion 56a forms an arcuate shape. The +4 arm 47 protrudes from the lower side 47a by a predetermined length.

The overhang ff1H of the acting portion 56a is set to a size such that the bottom surface 50 of the second moving shoe 49 and the acting portion 56a come into elastic contact with each other when the lid 9 is fully closed. This allows an upward bias to be obtained.

Therefore, according to the biasing member 56 of this embodiment, the first
When the lid 9 is tilted up as shown in FIG. 7 or when the lid 9 is tilted down as shown in FIG. .

On the other hand, as shown in FIG. 16, when the lid 9 is fully closed, the acting portion 56a of the biasing member 56 comes into elastic contact with the bottom surface 50 of the second moving shoe 59.

As a result, the lifting arm 47 is forcibly biased upward by the biasing member 56, and there is no risk of it shaking due to vibrations during travel. Further, since the biasing member 56 is made of a spring material, it is difficult to wear out and is very desirable in terms of durability.

In FIG. 14, the rotating body 93 provided on the first engagement body 54 of the lifting arm 47 functions in the same manner as the regulating portion 79 employed in the embodiment described above, as shown in FIG. 13.

That is, when tilting down, it is possible to pass from the opening 83a of the upper seven flange 83 of the guide rail 17 to the lower seven flange 84, and after the rotating body 93 completes passing from above to the opening 83a, further When the lid 9 moves back and forth, it is positioned between the upper and lower flanges 83 and 84 to control the vertical movement of the rear end of the lid, and when the lid 9 completes sliding forward, it faces the opening 83a and moves upward. Movement is now cancelled.

[Effects of the Invention] As explained above, according to the sunroof lid lifting device of the present invention, since the biasing member works when the lid is fully closed, the degree of wear can be significantly suppressed.
The lid can be reliably energized for a long period of time. This prevents rattling from occurring due to vibrations during driving, and improves the sense of quality.
