Ru. That is, in the state shown in figure c, the roof surface 1
The rear half 2a of the opening is opened. At this time, the front surface of the rear guide member 12 engages with the rear surface of the front guide member 16. After this, the cable 10a is further pulled forward, the front guide member 16 is pushed forward by the rear guide member 12, and the guide shaft portion 8b of the front slide panel support 8 is aligned with the vertical portion 19a of the guide hole 19. along the guide hole 19.
reaches the horizontal part 19b. This will cause link 1
3, 17, and 18 are raised up and facing vertically, resulting in the state shown in figure d. At the same time, the rear guide member 12
The locking portion 12a of the link 17 and the locking portion 17c of the link 17 engage with each other. After this, the guide shaft portion 8b moves forward in the guide hole 19b, and the rear slide panel support 9 and the front slide panel support 8 are locked by the respective locking portions 12a and 17c, and are integrated. The front part of the front guide member 16 is housed in a box 7 provided at the lower part of the roof surface 1.
At the same time, the main body 8a of the front sliding panel 3 and the front sliding panel support 8 is the main body 9 of the rear sliding panel 4 and the rear sliding panel support 9.
It moves forward on the roof surface 1 together with a, and is superimposed on the roof surface 1. As a result, as shown in FIG. 3e, the opening front half 2b of the roof surface 1 is also opened, and the slide panel is fully opened.

Next, when closing the slide panel, from the state shown in Figure 3 e, use the cable 1
Move 0a backwards. When the cable 10a is moved rearward, the rear slide panel support 9 and the front slide panel support 8 move backward as one unit because they are locked by the locking portions 12a and 17c. At the same time, the slide panels 3 and 4 are also moved backward, resulting in the state shown in FIG. 4D, and the opening front half 2b is closed. Further, when the guide members 12 and 16 move backward, the guide shaft portion 8b of the front slide panel support 8 comes into contact with the rear end of the horizontal portion 19b of the guide hole 19, so that only the lower portion of the link 18 moves backward. Therefore, the link 18 is tilted, and the guide shaft portion 8b moves downward and is locked at the vertical lower end 19a of the guide hole 19. On the other hand, the locking part 12a
and 17c are separated from each other by the inclination of links 13 and 17. In this way, the locking part 1
2a is separated from the front slide panel support 8,
The now movable rear slide panel support 9 moves backward, and is moved to a position where the rear slide panel 4 covers the rear half of the opening 2a, as shown in FIG. 3b. During this time, the guide shaft portion 9d of the rear slide panel support 9 moves backward along the guide piece 11a, and the rear slide panel 4 is guided in movement with its rear end raised. Guide piece 11
When reaching the rear end of a, the guide piece 1

In this state, the rear slide panel 4 comes into contact with the end of the back door 5, and the opening 2 in the roof surface is completely closed.

In this way, according to this sliding roof device, since the slide panel S is divided into two, the area of the opening 2 can be opened up to two-thirds of the area of the roof surface 1, and the roof surface 1 opening 2 can be made wider. In addition, guide members 16 of the pair of front slide panel supports 8 and guide members 12 of the pair of rear slide panel supports 9 are movably provided on a pair of guide rails 11 extending in the longitudinal direction of the axis. By moving the cable 10a, which also serves as the guide member 11 and is locked to the guide member 12, in the front-back direction, the front slide panel support 8 and the rear slide panel support 9 are interlocked to open and close the opening 2. This method can simplify the structure compared to the case where separate guide rails and drive parts are provided for each of the slide panel supports 8 and 9. Furthermore, each slide panel support 8, 9 is movably provided on the same guide rail 11, and by the operation of each link mechanism of each slide panel support 8, 9, each slide panel 3, 4 is lifted upward, and both This is a method in which the slide panels 3 and 4 are stacked and moved onto the roof surface 1 to open the opening 2, and each slide panel 3 and 4 is lowered by the operation of each link mechanism to close the opening 2. Therefore, it does not require much space in the ceiling below the roof surface 1, and can be stored within a relatively narrow width. Therefore, a good indoor height can be ensured, resulting in excellent livability. Further, when the back door 5 is opened, Fig. 1c
As shown in the figure, a wide, integrated opening is formed from the top of the vehicle body to the rear side, making it extremely convenient, especially when loading and unloading cargo.

(Effects of the Invention) As described above, according to the slide panel according to the present invention, a wider roof opening can be obtained by dividing the slide panel into two parts. In addition, a pair of front slide panel supports and a pair of rear slide panel supports are slidably attached to a pair of guide rails extending in the longitudinal direction of the vehicle, so that the guide rails can also be used as guide rails. This method allows the front slide panel support to be operated in conjunction with the operation using the operating cable, which simplifies the structure.
Furthermore, the front and rear slide panel supports are slidably attached to the same guide rail, and the front and rear slide panels are moved up and down by the operation of each link mechanism, and when the opening is opened, the front and rear slide panels are moved up and down. When it is lifted upward and placed on the roof surface, and the opening is closed, the front
Since the rear slide panel is in a lowered state, it does not require much space in the ceiling below the roof surface, and can be stored within a relatively narrow width, ensuring a good interior height.
