DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sliding roof structure for a vehicle, which is provided with a movable lid in a roof opening formed in a roof panel.

Conventional sliding roof structures for vehicles of this type include:
For example, as shown in FIG. 1, a movable lid 3 is inserted into a roof opening 2 formed in a roof panel 1, and a frame 4 is attached to the lower surface of the roof panel 1, and the frame 4 and the roof panel 1 are connected to each other. A housing portion 5 for the movable lid 3 is formed between the two and at the rear of the roof opening 2, and a pair of guide rails 6 extending in the longitudinal direction of the vehicle body are installed on both left and right sides of the frame 4. The movable lid 3 is supported slidably along the rail 6, and when the movable lid 3 is opened, the movable lid 3 is slid toward the rear of the vehicle body along the guide rail 6 and is stored in the storage section 5. There is something. In addition, as shown in FIG. 2, another conventional type applied to vehicles with a high vehicle height is a system in which guide rails 6 extending in the longitudinal direction of the vehicle body are laid on both sides of a roof opening 2 formed in a roof panel 1. And this guide rail 6
There is a vehicle in which a movable lid 3 is slidably supported along the vehicle body, and the roof opening 2 is opened and closed by sliding this movable lid in the longitudinal direction of the vehicle body. See "Automotive Engineering Handbook <Part 6>".

However, in such conventional retractable roof structures for vehicles, the movable lid 3 is stored inside the roof panel 1 in the former type, so the storage space for the movable lid 3 is limited. In order to ensure this, the frame 4 must be arranged so as to cover the entire roof panel 1, which has the disadvantage of narrowing the head clearance in the vehicle interior.
Since the guide rail 6 was laid on the roof panel 1, the guide rail 6 remained protruding above the outer surface of the roof panel 1 even when the movable lid 3 was closed, and there was a risk that the appearance quality would be impaired. Moreover, the presence of the guide rail 6 protruding from the outer surface of the roof panel 1 increases air resistance when the vehicle is running, and also causes wind noise.

The present invention has been made based on the above points, and its purpose is to support the movable lid flush with the general surface of the roof panel and to enable it to rise and fall upward from this general surface. For vehicles, a supporting elevating device is provided on the vehicle body side, a movable lid raised by the elevating device is slid toward the rear of the vehicle body by a slide mechanism, and the movable lid is held above the roof panel. In the movable roof structure, the elevating device has a rotating member supported by the movable lid or the vehicle body side member, and the slide mechanism is supported by the vehicle body side member and extends upward from the front end toward the rear. The head clearance in the vehicle interior can be reduced by having a guide rail having a shape that is inclined at least horizontally and then changing its direction at least horizontally, and a slider that is supported by the movable lid and slides inside the movable lid. By keeping the movable lid to the minimum necessary and eliminating external protrusions on the roof panel when the movable lid is closed, the appearance quality is maintained and wind noise is effectively prevented. To minimize the air resistance of a vehicle body when a movable lid is opened by keeping it horizontal to a panel. An object of the present invention is to provide a sliding roof structure for a vehicle.
