And an inward groove 8 for engaging the terminal of the roof lining 7 is formed at the opposite inside end. Then, on the groove 8, an outward groove 9 is formed.
Are formed, and an inward groove 10 is formed in a state facing the outer position of the outward groove 9. Further, an inward groove 12 for the shade 11 is formed above the outward groove 9.

Of the pair of grooves 9 and 10 facing each other in the vehicle width direction, a part of the outer groove 10 is cut out, and a stopper 13 is attached thereto. The stopper 13 includes a pair of front and rear inclined walls 14 and 15 inclined rearward.
The lower end of the front inclined wall 14 closes the groove 10, and the rear inclined wall 15 opens the groove 10.

At the center of the front rail 5 located on the front side, which is "one side" of the opening 2, a motor 16 as a "drive unit" is provided. A cable 17 (FIGS. 6 to 9) is routed from the motor 16 to each side rail 3. One end of the cable 17 reaches the corner member 4 from the motor 16 while being protected by a guide pipe 18 (FIG. 1), and passes through the inward groove 10 of the side rail 3 from there. The other end of the cable 17 is also protected by the guide pipe 18 while the motor 1
6 extends below the flange 6 of the side rail 3. Each cable 17 is engaged with a gear of the motor 16 and is sent out in the front-rear direction according to the rotation direction of the motor 16.

The side rail 3 is provided with a slider 19 and a hook 20 which move back and forth together with the cable 17 while being connected to the cable 17. As shown in FIGS. 8 and 9, the slider 19 and the hook 20 move back and forth with both ends engaged in the pair of grooves 9 and 10. An outwardly protruding guide pin 21 is provided at the upper end of the slider 19, and an engaging portion 22 that opens forward is recessed on the front surface of the hook 20.

On the other hand, guide members 24 extending in the front-rear direction are fixed to the lower surfaces of the right and left ends of the lid 23 provided in the opening 2. The guide member 24 is formed with a guide groove 25 having a substantially inverted “H” shape. A cap member 26 (not shown in FIGS. 2 to 5) having a U-shaped cross section that is open outward is attached to the guide groove 25. The cap member 26 is a molded product insert-molded with respect to the guide member 24.
The edge of the guide groove 25 is sandwiched. Then, with the cap member 26 interposed therebetween, the guide pin 21 provided at the upper end of the slider 19 is engaged with the inside of the guide groove 25 from the inside, and is movable in the guide groove 25.

And, at the front end of the guide member 24,
A front leg 27 is formed, and the lower end of the front leg 27 is engaged with the outward groove 9 as shown in FIG.
The lower end of the front leg 27 has an elliptical cross section, is movable along the groove 9, and can rotate (change the angle) in the groove 9.

At the intermediate position of the guide member 24, the inclined wall 1 before and after the stopper 13 fixed to the side rail 3 is provided.
An intermediate leg 28 that moves up and down between 4 and 15 is formed. The lower end of the intermediate leg 28 moves only obliquely up and down along the inclined walls 14 and 15, and movement in the front-rear direction is restricted.

Further, a rear leg 29 is formed at the rear end of the guide member 24. When the lower end of the rear leg 29 is engaged with the engaging portion 22 of the hook 20 at the lower end, the vertical movement of the rear leg 29 is restricted.

Next, the operation of the lid 23 will be described in order.
First, at the fully closed position (FIG. 2), the guide pin 21 of the slider 19 is in contact with the front end of the guide groove 25, and the opening 2 is completely closed by the lid 23. Also, the lower end of the rear leg 29 is the engaging portion 2 of the hook 20.
2 is engaged. The guide pin 21 abuts on the front end of the guide groove 25, the rear leg 29 engages with the hook 20, and the intermediate leg 28 is located in the stopper 13. Rattling is prevented.

Next, the motor 16 is rotated to rotate the cable 1.
When 7 is sent to the rear side, the slider 19 and the hook 20 move rearward. When the guide pin 21 comes to an intermediate position of the guide groove 25, the rear end of the lid 23 is
And rises to the tilt-up position (FIG. 3) around the lower end of the front leg 27.

Further, by moving the slider 19 backward,
When the guide pin 21 is brought into contact with the rear end of the guide groove 25,
The lid 23 is at a flap position (FIG. 4) in which the rear end is lower than the opening 2. At the flap position, the middle leg 28
The lower end of the guide groove 21 is located below the rear inclined wall 15 and can move rearward. When the slider 19 is further retracted from this state, the guide pin 21 remains in contact with the rear end of the guide groove 25. , The lid 23 slides into the roof 1 behind the opening 2 to reach the slide storage position (FIG. 5). still,
In the slide storage position, the front end of the lid 23 is also slightly lowered so as not to interfere with the rear edge of the opening 2.

Then, as shown in FIG. 10, in order to return from the slide storage position to the original fully closed position, the motor 16 is reversed and the slider 19 is moved forward. The guide pin 21 moves to the flap position while engaging with the rear end of the guide groove 25. When it comes to the flap position, there is nothing to press the rear end of the lid 23 from above, so the guide pin 21 moves forward in the guide groove 25 and returns to the fully closed position after passing through the tilt-up position.

In this embodiment, the fully closed position is the guide groove 2
5, the rear end of the lid 23 approaches the rear edge of the opening 2 from above from the tilt-up position to the flap position, as described above, since the tilt-up position and the flap position are located behind the front end. Then, after passing through the edge, it becomes the flap position, and then becomes the slide storage position. Therefore, when the rear end of the lid 23 descends, there is a possibility that a foreign matter (such as a brush for car washing) X shown in FIG.

However, in this embodiment, even if the foreign matter X is sandwiched between the rear end of the lid 23 and the rear edge of the opening 2, the rear end of the lid 23 immediately rises and turns over, so that the rear end of the lid 23 is in the tilt-up position. It is designed to stop. Therefore, the lid 23 that has once been raised does not return to the fully closed position and return again to pinch the foreign substance twice, and it is possible to reliably prevent the mechanism from being damaged.

In the case of such a lid 23, there are two modes for sandwiching the foreign matter X. One is when the foreign substance X is sandwiched between the front end of the lid 23 and the front edge of the opening 2;
The other is, as described above, the rear end of the lid 23 and the opening 2.
This is a case in which the foreign matter X is sandwiched between the object and the trailing edge. In the case of being pinched at the front end, it is largely inverted rearward to facilitate removal of the foreign matter X. In the case of pinching at the rear end, the pinch is turned upside down and stopped at the tilt-up position as described above. Recognition of these two sandwiches is performed by detecting the position of the lid 23 by the motor 16.

That is, the motor 16 can detect the position of the lid 23 based on the count number with the fully closed position as the reference point, and can also detect the trapping of the foreign matter X by increasing the load (current / voltage) applied to the motor 16. It has become. Therefore, pinching at the rear end of the lid 23 can be recognized separately from pinching at the front end.

In order to detect entrapment at the rear end of the lid 23, a touch type or pressure type sensor S as shown in FIG. It is also possible to detect the entrapment and output an inversion signal to the motor 16.

In the above-described embodiment, the type in which the front end of the guide groove has the fully closed position is described as an example. However, the fully closed position is located in the middle of the guide groove, the tilt-up position is on the front side, and the flap is on the rear side. A type having a position may be used.

[0038]

According to the present invention, when a foreign object is caught between the rear end of the descending lid and the rear edge of the opening, the rear end of the lid rises, turns over, and stops. It does not fall again and pinch foreign matter, and damage to the mechanism can be reliably prevented.
