It is designed to shorten and move in conjunction with movement, and the opening/closing body is brought closer to the rear roof, but the structure is complicated because it uses threaded cables, screw telescopes, etc., and it is necessary to simplify assembly. It is not possible to reduce the cost of equipment.

Therefore, as shown in FIG. 5 showing the closed state of the roof opening 81 and FIG. 6 showing the opened state, the opening/closing body 82 is
It is conceivable to form one of the guides 83 and 84 to an appropriate shape and provide the rear end lowering means 85 when the opening/closing body 82 is opened on the guide itself.
If the single guide 84 is provided with the rear end lowering means 85, the vertical height H of the guide becomes large, resulting in a problem of narrowing the space inside the vehicle.

The present invention has been developed to solve the above-mentioned problems, and an object of the present invention is to provide a sliding slide for a vehicle that can simplify the structure and assembly, and at the same time secure the space inside the vehicle. It is to provide a type roof structure.
