As shown in FIGS. 1 and 2, this slide device includes a frame 5 having an opening 4 connected to the opening 3 formed in the vehicle roof 2 at the side edge of the opening 3.
A front slider 7A attached to the front part of the lid 6 and a rear slider 8 attached to the rear part of the lid 6 via a flap link 9 are slidably assembled to the left and right guide rails 1A disposed through the lid 6. As shown in FIG. 2, the left and right guide rails 1A have left and right front sliders 7 at the middle upper part in the vehicle width direction.
A first guide groove 15 into which the slider A is fitted, a second guide groove 16 into which the left and right rear slider 8 is fitted into the lower outer side of the first guide groove 15, and a wire 13 outside the second guide groove 16. A wire guide groove 17 to be fitted into the first guide groove 15 is provided, and a finisher guide groove 18 for slidingly guiding a sunroof finisher (not shown) having a light shielding function is provided inside the first guide groove 15. The left and right guide rail 1A has a front portion bent obliquely upward and a front tapered portion 19 that smoothly extends from a straight portion at the rear thereof. Reference numeral 20 denotes left and right lid brackets attached to the sides of the lid 6, with a front slider stay 21 at the front of the outer edge thereof and a movable link plate 22 of the flap link 9 at the rear of the outer edge.
A fixed link plate 24 is provided with one end attached via a lid side pin 23, and a fixed link plate 24 is provided at the middle part of the outer edge of the fixed link plate 24 in the front and rear direction. A stopper pin 26 is provided in the penetrating insertion hole 25 via a flange 27 to be received when the lid 6 is assembled and when the lid 6 is fully closed. A flange 28 is bent inward at the lower end of the front slider stay 21, and a slider main body 30 made of synthetic resin is attached to the flange 28, forming the left and right front sliders 7A. Furthermore, a slider 32 for operating other functional parts of the sunroof, such as a wind deflector (not shown), is provided on the outer side of the lower outer edge of the left and right lid brackets 20 in front of the left and right front sliders 7A. There is. The slider 32 is configured to pass over a communication groove 33 that communicates with the second guide groove 16 between the first guide groove 15 and the wire guide groove 17 of the left and right guide rail 1A. Numeral 34 is a stopper mechanism consisting of a wedge 35 attached to the left and right guide rails 1A and a contact member 36 attached to the flap link 9.
The lid 6 has a function of suppressing the forward movement of the lid 6 by the contact between the lid 6 and the contact member 36, and a function of applying an auxiliary force to the upward movement of the rear portion of the lid 6 by the flap link 9. Wedge 35 is left and right guide rail 1
It is stored in the passage groove 33 of A and is fixed to the bottom surface of the passage groove 33, and the upper rear end surface is formed into a forward-slanted tapered surface 35a. Contact member 36
is extended from the front part of the lid-side fixed link 24 of the flap link 9 so as to be inserted into the passage groove 33, and is formed in a forward-slanted shape. Reference numeral 37 denotes a rear stopper made of a soft elastic material such as rubber or synthetic resin, which is attached to the rear ends of the left and right guide rails 1A and receives the left and right rear sliders 8 when the lid 6 is in the fully open position.

According to the above embodiment structure, when the sunroof switch installed around the driver's seat (not shown) is operated to the open side when the lid 6 is fully closed as shown by the solid line in FIG. Although the power is transmitted from the left and right wires 13 to the left and right rear sliders 8, and the left and right rear sliders 8 move backward on the left and right guide rails 1A, the stopper pin 26 is inserted into the insertion hole 25.
Since the lid 6 comes into contact with the rear wall and remains stationary without moving rearward, the movable link plate 22 of the flap link 9 rotates rearward around the lid side pin 23, and the rear part of the lid 6 moves toward the left and right front sliders 7A. , and the stopper pin 26 comes out of the insertion hole 25. As the left and right rear sliders 8 continue to move backward, the left and right front sliders 7A move diagonally backward and downward on the front tapered portion 19, and the front part of the lid 6 is lowered, so that the entire lid 6 is shown by the dashed line in FIG. While moving to the inside of the vehicle roof 2, the left and right front sliders 7A
and the left and right rear sliders 8 are the left and right guide rails 1A.
The lid 6 is housed in the space 38 between the rear part of the opening 3 of the vehicle body roof 2 and the frame 5, as shown by the imaginary line in FIG. It will be released. Furthermore, when the aforementioned sunroof switch is operated to the closed side in the open state of the lid 6 with the openings 3 and 4 open, the geared motor is reversely rotated, and the left and right front sliders 7A and the left and right rear sliders 8 are moved onto the left and right guide rails 1A. When the lid 6 moves forward from the position shown by the imaginary line in FIG. However, due to this sliding contact, an upward auxiliary force (upward auxiliary force) is applied to the rear part of the lid 6, and under the action of this upward auxiliary force, the movable link plate 22 moves forward around the lid side pin 23. The rear part of the lid 6 moves upward around the left and right front sliders 7A, and the left and right front sliders 7A move forward on the front tapered part 19. Furthermore, the stopper pin 26 is stored in the insertion hole 25, and the lid 6 is moved upwardly around the left and right front sliders 7A. The upper surface of the lid 6 is smoothly aligned with the upper surface of the vehicle roof 2, as shown by the solid line in FIG. closed state).

Here, considering the case where the left and right guide rails 1A with the front tapered part 19 are used and the case where a straight guide rail without the front tapered part is used, the lid 6
In the fully closed state, the left and right front sliders 7A and the left and right rear sliders 8 are connected as shown in FIG.
Draw a straight guide rail with a dotted line. Then, in the case of this straight guide rail, the bottom of the frame 5 will be lowered toward the inside of the vehicle by the dimension H compared to the case where the left and right guide rails 1A of the above embodiment are used, and this will cause the roof to be lowered. The thickness increases by the dimension H. Therefore, when the front portions of the left and right guide rails 1A are bent obliquely upward as in this embodiment, the rear portions of the left and right guide rails 1A are positioned above the straight portions of the guide rails by a distance H. Therefore, the thickness of the roof can be reduced accordingly. That is, assuming that the height of the vehicle interior is constant, the thickness of the roof can be reduced by at least the dimension H, and the height of the vehicle can be lowered by that thinner amount.

Effects of the Invention As described above, according to the present invention, a predetermined range of the front end portions of the left and right guide rails is bent diagonally upward, and the left and right guide rails are provided with a front tapered portion that smoothly extends from the straight portion at the rear thereof. Because of this, the straight part of the left and right guide rails and the front tapered part are connected smoothly without any parting gaps or steps, without causing any hindrance to the vertical movement of the front part of the lid. The front slider slides smoothly on the connecting part between the linear part of the left and right guide rails and the front taper part without rattling, and when the lid is closed, the front part of the lid is displaced upward by the front taper part, and the stopper mechanism and flap link are Also, when the lid is opened, the rear part of the lid is displaced downward by the stopper pin fitting mechanism into the insertion hole and the flap link, and then the front part of the lid is displaced downward by the front taper. The lid opens and closes smoothly and accurately. Furthermore, like the conventional structure, a notch is formed in the upper wall around the left and right front flap guides of the guide groove, and this notch is covered with a left and right cover separate from the left and right guide rails. There is no need for a structure that prevents the slider from shaking in the vertical direction, and the opening/closing performance of the lid can be improved with a simple combination of the front taper part, the insertion hole into which the stopper pin fits, and the stopper mechanism. The number of parts is small and assembly work is easy.
There are novel effects such as being able to provide a slide device at low cost. Moreover, by forming the front tapered part, the rear parts of the left and right guide rails are positioned upward, which allows the roof to be thinner, which has the advantage of lowering the vehicle height without narrowing the interior height. There is also.
