To assemble the sunroof device for a vehicle having the above configuration, assemble the device with the main body of the opening/closing body 10 removed.
Bring it into the vehicle interior and bring it close to the roof opening AI from below. Once the 0 position is determined, the mounting bracket) A3 will come into contact with the flange 20b of the frame 20 and the position will be aligned, so screw it in with the screw 20c. do.

The main body of the opening/closing body 10 is connected to the position of the insertion hole 12a of the tilting arm 12 and the unit frame 20. Working hole 2 of guide rail 21
0d and the insertion hole 21c are aligned with each other.
Position the opening/closing body 10 and move it to the roof opening AI.
The bolt 14 is pressed against the upper surface of the tilting arm 12 from the outside in the L direction, and the bolt 14 is inserted through the working hole 20d and the insertion hole 21c, and then inserted into the insertion hole 12a of the tilting arm 12. Screw it into the nut 13, and then tighten it (Nara) 1
3 is moved laterally to adjust the position and then fastened, the main body of the opening/closing body 10 is fixed. Thereafter, the working hole 20d is closed with a resin cap 20e to prevent rain and the like from entering.

Next, the operation will be explained.

In the fully closed state of the opening/closing body 10 shown in FIG. 2 and FIG.
is locked in that position and cannot be moved.

From this state, when the drive unit 22 drives the guard cable 23 vertically to the right (backward in the vehicle) in FIG. 10, the input gear 34a meshing with the guard cable 23 rotates the drive gear 34 Therefore, the female screw hole 34b is rotated, and the elevating member 36, in which the bolt portion 36a is engaged with the female screw hole 34b, is raised.

When the elevating member 36 rises, the elevating drive lever 35 is pushed up and tilted via the sliding member 1@37, and the pivot 35b connecting the elevating drive lever 35 to the elevating arm 12 rises, causing the opening/closing body 10 to rise. In this case, the amount of movement of the elevating member 36 is increased and transmitted to the pivot 35b, so the elevating stroke of the elevating member 36 is reduced, and the opening/closing body 10
can be tilted.

The pivot 35b is the pivot 3 of the base 35a of the up/down drive lever 35.
However, the opening/closing body 10 and the raising/lowering 7-me 12 do not simply tilt around the base end 12b, but are displaced according to the trajectory of the pivot 35b, and the opening/closing body 10
The instantaneous center of is at a position spaced apart from the position of the connecting member 32. The displacement between the respective members is absorbed by the connecting member 32 swinging and the sliding piece 37 swinging and sliding within the engagement groove 35c of the raising/lowering drive lever 35 without interference.

Furthermore, when the opening/closing body 10 tilts and opens, the front end of the opening/closing body 10 takes a trajectory that moves backward relative to the sealing surface of the flange A2 at the front of the roof opening A1, so that the sealing material 11 may rub or bite. There will be no breakage.

When the opening/closing body 10 comes to the verge of full tilting opening/closing as shown in FIG. 1 or FIG. As such, the pushing end 15b comes into contact with the pushed end 42b of the operating bin member 42. When the connecting block 15 further moves to the right in FIG. 3, the pushing end 15b
The slanted surface pushes the slanted surface of the pushed end 42b of the operating bin member 42, thereby moving the operating bin member 42 upward.

When the operating bin member 42 moves upward in FIG. 7, the interlocking member 43 is reversed, and the lock pin member 41 moves downward in FIG. Fitted into the recess 15a, the opening/closing body 10 becomes fully open by tilting, and the supporting base 3
0 is disengaged from the notch 21d of the guide rail 21, and the restriction on the forward and backward movement of the opening/closing body 10 is released.

When the guard cable 23 moves further from this state, the support base 30 is connected to the guard cable 23 via the engagement/disengagement means 40 and pulled, and the tilting arm 12 of the opening/closing body 10 also moves together with the support base 30. The opening/closing body 10, which is tilted and opened as shown in Fig. 13, moves to the rear of the roof opening AI, and the front part of the roof opening A1 opens, and slides and opens fully as shown by the imaginary line in Fig. 3. be able to.

In the fully open state, the raising/lowering arm 12 fits into the hollowed out part A5 of the roof opening At, and the opening/closing body 1 is moved until the central part of the main body of the opening/closing body 10 comes sufficiently close to the central part of the rear edge A4 of the roof opening A1.
O can be moved back and the roof opening A1 can be opened wide.

When closing the opening/closing body IO, move the guard cable 23 in the opposite direction to the above, and the opening/closing weight is 0 as shown in FIG.
The opening/closing body 10 is closed from the fully opened state by sliding to the tilted open state shown in FIG. Then, the roller 41a of the lock bin member 41 of the locking/disengaging means 40 fits into the notch 21d of the guide rail 21, and the slope of the recess 15a of the connecting block 15 presses the connecting end 4° 1b, and the spring 42a With the addition of elastic force, the roller 41a
is further pushed into the notch 21d, whereby the engaging/disengaging means 40
is detached from the connecting block 15 and is locked to the guide rail 21.

When the guard cable 23 moves further, the drive gear 3
4 rotates, and the elevating member 36 descends. When the elevating member 36 descends, the raising/lowering drive lever 35 falls down, and the opening/closing body 10 tilts and closes in the opposite direction to when it is tilted and opened. The connecting member 32 moves following the movement of the base end 12b of the tilting arm 12 of the opening/closing body 10 until the opening/closing body 10 is fully closed.

Even when the opening/closing body 10 is tilted and fully closed, the front end of the opening/closing body 10 takes a trajectory such that it approaches the sealing surface of the seven langes A2 at the front of the roof opening A1 from the front, so that the sealing material 11 The sealing material 11 is in close contact with the sealing surface, and reliable watertightness can be obtained without rubbing or cutting due to cutting.

If either the opening/closing body 10 or the roof panel A is displaced due to a load applied to it, the opening/closing body 10 and the roof panel A will be dislocated because the frame 20 is fixed at key points of the 7 langes A2 with mounting brackets) A3. The two are displaced integrally, so there is no need for only one side to be displaced and a step to be created between it and the other, deteriorating the appearance quality or causing concerns about rigidity.

In the above embodiments, the opening/closing body opens and closes by tilting and also slides to open and close, but it goes without saying that the opening/closing body may open and close only by tilting.

"Effects of the Invention" According to the vehicle sunroof device according to the present invention, since the base end of the opening/closing body is supported via the connecting member and the opening/closing body is tilted by the tilting drive lever, the opening/closing body is tilted. The sealing member provided at the front end of the opening/closing body does not rub against or hit the sealing surface when opening and closing, and the sealing member is not damaged or fatigued, making it possible to obtain good watertightness. can. Since the center of rotation of the opening/closing body can be positioned further forward than the support part where the actual connecting member is located using the link mechanism, the front end of the opening/closing body can be positioned in front of the support part, and the roof can be adjusted accordingly. The front part of the opening can be brought closer to the windshield glass to make the opening larger.
