Although there is a risk of swinging in the vehicle width direction with the central portion (the pivot 41b) as a fulcrum, the steady rest 48 is provided on both side edge portions 2 of the rear door 20.
Since it is connected to the 8 side, the steady rest 48 can restrain the rear door 20 from swinging in the vehicle width direction. When the rear door 20 is in the front opening operation, the steady rest means 48 uses the intermediate position between the front closed position and the front open position of the rear door 20 as a boundary, and the rear door 20 on the front closed position side. Is urged in the front closing direction, and is urged in the front opening position side in the front opening direction. Therefore, when the rear door 20 is closed to the intermediate position, the urging force of the steady rest 48 is obtained. As a result, the rear door 20 is closed to the front closed position, and a large driving force is not required.

When the roof 30 is open, the roof 30 is closed in the reverse order of the above-described opening operation. That is, the second locking means 7
0 in the restraint release state, and the electric motor 42 of the first opening / closing mechanism 40.
In the forward direction to bring the rear door 20 into the front open state.

After the rear door 20 is opened to the front, the roof opening / closing device is operated to gradually extend the front roof and the rear roof from the folded state and move them to the front to completely extend the front roof and the rear roof. Then, when the ceiling is formed, the operation of the roof opening / closing device is stopped.

Next, the electric motor 42 of the second opening / closing mechanism 40 is reversed. Swing about the pivot 41b of the hinge 41,
The rear door 20 is fully closed via the first locking means 60, the striker 52 is engaged with the second locking means 70, and the rear door 20 is closed.
Is constrained to a fully closed state, and the electric motor 42 stops rotating.

Although the second opening / closing mechanism 40 drives the rear door 20 from the front-closed state to the front-opened state via the first locking means 60 in the above-described embodiment, the first locking means 60 has been described. Alternatively, the second opening / closing mechanism 40 may directly drive the rear door 20 without going through. At this time, the driving force of the second opening / closing mechanism 40 is configured to be transmitted to the central portion of the rear door 20 in the vehicle width direction, and the first locking means 60 is also provided.
Are configured to keep the rear edge of the rear door 20 restrained.

Further, although the steady rest 48 is shown as being connected to the both side edge portions 28 of the rear door 20 via the first opening / closing mechanism 47, it is directly connected without the first opening / closing mechanism 47. You may make it connect with the both side edge parts 28 of the rear door 20.
