The gutter 28 moves relatively forward due to the long groove 73a, and the roof opening 1
A trowel is held that protrudes from below the rear end edge 17 of the trowel 1 toward the opening side.

The drive base 50 is moved from the state where the opening/closing body 20 is tilted and fully closed.
When moved to the left in FIG. 8 and returned, the opening/closing body 20
．． The cover plate 21 can be fully opened by moving it lvi in the opposite manner to the above. The gutter 28 also retreats in the opposite manner to the above.

As the opening/closing body 20 is tilted and opened/closed, the rear cover of the shade 60 is pulled up to the free end of the opening/closing body 20 via the spring 62, and the shade support member 61 swings around its base, causing the shade 60 to bend and close the opening/closing body 2. Opens and closes with °.

The drive base 50 is moved from the state where the opening/closing body 20 is tilted and fully closed.
When the drive base 50 is moved to the right in FIG.
Due to this movement, the holding pin 55 enters and fits into the fitting groove 26 of the holding member 27 fixed to the support frame 24 of the opening/closing body 20 from the front, and the free end of the opening/closing body 20 is displaced in the vertical direction. Hold it to suppress it. In this state, the door is completely closed.

When the brake base 40 is further moved to the right from the completely closed state, the cam follower 44 of the raising/lowering member 41 is moved to the groove-shaped cam of the drive base 50, as shown in FIGS. 9, 11, and 16(b). 53, the raising/lowering member 41 further falls down, and the rear end of the cover plate 21 and the sealing member 23 retract inward from the rear roof lO, and as shown in FIG.

The rear end portion 5 of the drive base 50 extends forward from the moving table 77.
A rack 77b is carved in an extension 77a that overlaps above 6. A moving table 7 is provided at the rear end/portion 56 of the drive base 50.
A rack 56a facing the rack 77b of No. 7 is carved.

A pinion 78 that meshes with the rack 77b and the rack 56a
The pinion 78 is pivotally connected to the brake base 76 by a pivot shaft 78a, and is engaged with the extension part 77a of the movable table 77 through a long groove 77c so as to be slidable back and forth.

The movable table 77 is biased forward with respect to the brake base 76 by a spring 79.

In this embodiment, when the opening/closing body 20 is fully closed and the drive base 50 approaches the brake base 76 as shown in FIG.
The rack 56a at the rear end portion 56 of the drive base 50 rotates the pinion 78, and the rack 77b and the moving table 77 are pulled out forward. Therefore, the gutter 28 is connected to the edge 17 of the roof opening 11.
Move forward and stand out.

When the opening/closing body 20 separates from the braking base 76 in order to tilt open/close, it is pulled away from the brake base 76 and the movable base 77
This causes the gutter 28 to retreat from below the edge 17 of the roof opening 11. In addition, in this second embodiment, the opening/closing body 20
Even if the drive base 50 is moved further rearward from the fully closed state, the movable base 77 (gutter 28) will not move forward due to a stopper (not shown), and the rack 56a and pinion 78 will vibrate.

In this way, any appropriate interlocking mechanism can be used.

[Effect of the invention] According to the vehicle sunroof device according to the present invention.

The gutter moves forward or backward only when necessary to catch water under the edge of the roof opening, so when the opening/closing body is tilted open/closed, the roof opening opens wide, improving comfort. .
