[Problems to be solved by the invention] In the above-mentioned tilting device, the front and rear
Since a mechanism is required to connect and interlock each set of lifting devices, the structure becomes complicated, and if the length of the cable between the lifting devices changes due to cable stretching, etc., the lifting operation may be disrupted. There is a problem in that it is easy to occur.

Therefore, in this invention, when tilting the sliding roof, the front edge of the roof is lifted only by the lifting device at the rear connected to the cable, and there is no rattling between the parts, and the sliding roof is tilted. To provide a sliding roof opening/closing device with a simple structure capable of smoothly opening/closing a roof, having a simple structure, and facilitating mutual assembly work.

[Effect of idea]

According to the present invention, the sliding roof is supported on the free ends of a pair of front and rear links pivotally connected to the front slider, and these front and rear links are connected to the front and rear of the rear slider connected to the drive means. They are linked to each other so that when the rear link is rotated, the rear edge of the sliding roof rises, and the front link also rotates in synchronization with the slider. The leading edge of the riding roof can also be raised slightly.

Therefore, the front edge of the sliding roof will not be lowered downward during the tilt operation, nor will it move forward or backward.

In addition, since the front and rear links are rotated synchronously by the rear slider connected to the drive means, tilting and lifting operations can be performed reliably, and the structure is simple and the number of parts can be reduced. Less is enough.

Furthermore, the front link and the rear link can be easily attached to the guide rail integrally with the front slider, and rattling between the parts can be minimized.
