It has the function of fixing and holding the end of the guide pipe to be inserted and guided to the end of the guide rail.

EXAMPLES The present invention will be described in detail below with reference to the drawings.

FIG. 7 shows an automobile sunroof structure and opening/closing means to which the present invention is applied. In the figure, 1 is a tilt lid, 2 is a slide lid, and 3 is a fixed roof panel. The sunroof panel is connected to the tilt lid 1 and the slide lid. It is composed of two lids, 2 and 2. A guide rail 4 is fixed to the vehicle body and guides the sliders 9, 17, etc., and a wire driven by a drive motor (not shown) is movably inserted into the guide rail 4. External drive member or slider 1
It is connected to 7. A front slider 9, which will be described later, is removably connected to a drive member (not shown) via a link with an elongated hole.

A bracket 6 is fixed below the tilt lid 1, and the bracket 6 and one end of the elevating link 7 are pivotally supported. The other end of the elevating link 7 is pivotally supported by one end of a front slider 9 fitted so as to be slidable within a slider guide 8 fixed to the vehicle body. One end of a link 10 with an elongated hole is pivotally supported at the other end of the front slider 9, and the other end of the link 10 with an elongated hole extends toward the rear of the vehicle. Further, the other end of the auxiliary link 11 that coaxially supports the shaft support of the lifting link 7 and the bracket 6 is connected to the elongated hole 1.
2 is loosely fitted.

On the other hand, the slide lid 2 is supported by support plates 13 and 14 at its front and rear positions, and two links 15 and 16 are attached to the rear support plate 14 in the front and back direction. Link 1
The other ends of 5 and 16 are provided so as to be slidable within the guide rail 4, and are connected to a drive wire to be driven by the elongated hole slider 17 via elongated holes 17a and 17b. has been done.

The basic operation of the tilt lid 1 having the above configuration is as follows. As the wire 5 moves to the right, the slotted link 10 and the front slider 9 first move to the right, and by the action of the elevating link 7 whose one end is pivotally supported by the front slider 9, the tilt lid 1 moves to the right. As shown in FIG. 8, it is rotated counterclockwise by a predetermined angle about a fulcrum 18 at the front end which is hinged to the fixed roof, and is in a tilted up state.
At this time, the auxiliary link 11 does not participate in the above-mentioned rotational movement, but merely contributes to maintaining the rigidity of the elevating link 7. On the other hand, when the tilt lid 1 rotates, the slider 17 with an elongated hole moves backward in conjunction with the front slider 9, but the links 15 and 1 on the slide lid 2 side
6 is running idle in the long holes 17a and 17b of the slider 17 with long holes (FIG. 7→FIG. 8), and the slide lid 2 does not perform any operation.

Next, when the tilt up operation accompanying the rotation of the tilt lid 1 is completed and the wire 5 further moves to the right, the links 15 and 16 attached to the slide lid 2 are opened in conjunction with the slider 17 with an elongated hole, as shown in FIG. The user lowers his/her posture while stepping and assumes a position that allows him/her to enter the underside of the roof panel 3. At this time, the connection between the end of the wire 5 and the link 10 with the elongated hole is disconnected, and the tilt lid 1 maintains a tilted-up position. Next, as the wire 5 moves, the slide lid 2 slides under the roof panel 3 as shown in FIG. 10, and the opening of the sunroof is completed. When closing the sunroof, the operation is the opposite of the opening operation described above, that is, the slide lid first slides to its original position, and then the links 15 and 16 rise to raise the slide lid 2 to the position of the roof panel 3. Subsequently, the front slider 9 on the side of the tilt lid 1 is slid to the left to move the elevating link 7 from the upright state shown in FIG. 8 to the laid down state shown in FIG. 7, and the tilt lid 1 is closed. During this time, the links 15 and 16 are running idle in the long holes 17a and 17b of the slider 17.

The basic concept of the automobile sunroof opening/closing device to which the present invention is applied has been explained above with reference to FIGS. 7 and 8. Below, the structure of the end portion that the rear end of the slide lid comes into contact with will be explained.
