Next, the operation of the sliding roof 2 will be explained.

As shown in FIG. 5, when the sliding roof 2 is in the tilted down position A and has been moved forward via the cable 9, the sliding shoe 25 comes into contact with the stopper, and the front part of the weather strip 42 is placed in front of the opening 3. It touches the front part of the roof.

At this time, the engaging part 40 of the movement regulating member 38 is not engaged with the engaged part 40A of the guide rail 4, and moves the sliding roof 2 backward, so that the lower surface of the fixed roof 1 behind the opening 3 It can be freely stored in a storage section 43 formed in the.

Further, the slider 11 is located approximately behind the slide roof 2, and the rear part of the slide roof 2 is located at the same level as the upper end of the slider 11.
Or, the lower rear end of the lifting link 20 is located at the front end of the linear guide groove 16, and the first guide portion 23 is located at the first cam groove 17.
The pair of left and right lifting links 20 are connected to each other by a drip rail 26, and are located within the guide rail 4 substantially parallel thereto.

When the slider 11 is moved forward from this state, the first guide part 23 slides in the first cam groove 17, so the elevating link 20 rotates upward around the rear lower end, and the slide roof 2
The rear part of the roof is raised to the same height as the fixed roof 1, and the opening 3 is placed in the closed position C as shown in FIG.

During this tilting operation, since the pair of left and right lifting links 20 are connected to each other by the drip rail 26, the tilting movements of the lifting links 20, that is, the left and right sides of the sliding roof 2, are synchronized or synchronized, and the opening 3 In the closed state, the gutter bottom 27 of the drip rail 26 is located below the opening with a downward slope.

Therefore, as shown by arrow E in FIG. 6, dripping rainwater, etc. is received by the drip rail 26 and drained by the drainage section 34 shown in FIG.
35, along the guide rail 4, and is discharged to the outside of the vehicle from a drainage hose (not shown) or the like.

At this time, as shown in FIG. 6, the lip 32 stops receiving the rebound water.

In conjunction with the tilting operation of the sliding roof 2, the movement regulating link 38 moves forward and upward, and the engaging portion 40 provided in the middle thereof engages with the engaged portion 40^.

When the slider 11 is moved further forward, the slide roof 2
performs a further tilt-up operation from the opening closed position C,
On the way, the first guide part 23 separates upward from the first cam groove 17, and even before it separates, the second guide part 24 engages with the arcuate portion 18A of the second cam groove 18, and the slide roof 2
guides the tilt operation.

Note that even if the sliding roof 2 is tilted upward from the opening closing position C to any position above, the engaging part 40 of the movement restriction link 38 is engaged with the engaged part 40A. The sliding roof 2 does not wobble even when subjected to resistance, and remains immovable for 3 days, so it supports the middle part of the sliding roof 2.

Even during this tilt amplifier operation, since the pair of left and right lifting links 20 are connected to each other by the drip rail 26, they operate in synchronization or at the same time.

In the tilt-up position shown in FIG. 4, the drip rail 26 has a steeper downward slope, and its upper lips 31 and 32 reliably catch rainwater and the like flowing down as shown by arrow F in FIG. 7.

In addition, slider 11 is used to tilt down from the tilt amplifier.
In the tilt-down state, the sliding roof 2 and the drip rail 26 are moved together in the housing section 4.
It can be accommodated in 3.

In the above-described embodiment, the means for tilting the sliding roof 2 may be operated by a cam mechanism other than the illustrated cam mechanism, as long as the tilting operation means is performed by the up-and-down movement of the elevating link 20 as the slider 11 moves back and forth. The link 20 may be directly supported.

Further, the drip rail 26 may have the shape shown in FIG. 11. Furthermore, the front support, intermediate support, etc. of the sliding roof 2 can be freely designed.

Referring to FIGS. 12 and 13, a technique is disclosed in which the height adjustment means of the sunroof is improved.

In this disclosed technology, the height is adjusted by moving the guide rail 4 up and down.

That is, the guide rail 4 and the guide rail 101 of the sunshade 100 are made independent, the guide rail 101 is attached to the mounting frame 5 by a seaming weld 102, and the guide rail 4 is adjusted by the adjustment pole l-103, then the It can be attached using a tool 105 or the like.

To explain the height adjustment procedure, remove the slide roof 2 from the guide rail 4, loosen the Nando 104,
Adjustment bolt 103 screwed into back nut 1048
Adjust the height of the guide rail 4 through the nut 104.
The sliding roof 2 is tightened and the sliding roof 2 is attached, and the heights are confirmed to match. According to this, the space between the sliding roofs 2 can be minimized and the roof unit can also be made thinner.

(Effects of the Invention) The present invention is as described above, and the drip rail accompanying the sliding roof has an abbreviated cross-section having a gutter bottom and a rising part, and when the sliding roof is fully closed, the gutter bottom is Since the rear slopes downward and has an upright part on the slope side, the total thickness of the bag-shaped storage part that stores the sliding roof and drip rail can be reduced, which increases the headroom inside the car. It can improve livability.

Furthermore, since the bottom of the gutter is sloped downward at the rear and has an upright part on the sloped side, rainwater etc. that flow down in the fully closed state are reliably prevented from scattering or leaking into the passenger compartment.

Furthermore, since the drip rail connects the pair of left and right lifting links provided on the slider to each other, synchronized movement of the slider can be ensured, and the tilting operation of the sliding roof can also be performed without any play in each part. However, synchronization or synchronization is ensured, and the rigidity of the lifting link is increased, and this is also significant in terms of manufacturing, as the lifting link can be made of a thinner material.

Since the present invention has the above advantages, it is very useful as a sunroof device for a vehicle.
