As shown, the roof lid 6 can be stored in a second storage position substantially along the front surface of the rear seat back 33b.

  Of course, depending on the length adjustment of the center link mechanism 13, the roof lid 6 is stored at a position above the standard first storage position or at an intermediate position between the first storage position and the second storage position. It is also possible to do.

  As described above, according to the sunroof structure of the present embodiment, since the opening / closing mechanism 11 of the roof lid 6 is disposed below the rear roof 3 and the center roof 4, this opening / closing is performed even when the roof lid 6 is opened. Since the drive mechanism 11 is not exposed to the outside and the center roof 4 is integrally formed with the front roof 2 and the rear roof 3, the boundary between the center roof 4, the front roof 2 and the rear roof 3. There is no step in the portion, and therefore the appearance can be further improved.

  Further, since the opening / closing drive mechanism 11 is composed of a pivotal link mechanism comprising a side link mechanism 12 and a center link mechanism 13 that are pivotable in the front-rear direction, a guide rail provided on a conventional roof. Since the space occupied on the lower surface side of the roof can be made smaller than that of the slide structure with the guide roller provided on the roof lid, the head clearance in the vehicle compartment can be increased.

  Further, since the roof lid 6 is opened and closed from the fully closed position to the retracted position on the vehicle interior side with the vehicle body side connection point of the side link mechanism 12 as the rotation center, the roof lid is mounted on the rear roof as in the prior art. Unlike what is stored in the roof, the roof appearance is not impaired.

  Moreover, by storing the roof lid 6 in a substantially horizontal state above the rear seat cushion 33a, the roof lid 6 functions as a tonneau board, so that the luggage placed on the rear seat cushion 33a can be made difficult to see from the outside. The appearance can be improved, and an anti-theft effect can be obtained.

  Further, by storing the roof lid 6 almost along the front surface of the rear seat back 33b, the rear seat back 33b can be opened to make it difficult to access the trunk room.

  Furthermore, since the roof lid 6 can be selectively stored in the horizontal state and the position along the front surface of the rear seat back 33b by adjusting the expansion and contraction of the center link mechanism 13, an appropriate storage position corresponding to the storage state of the luggage can be obtained. Can improve convenience.
