Description

TECHNICAL FIELD The present invention relates to a drainage structure for a sunroof.

<Prior Art> Generally, there is known a sunroof in which a sunroof panel that can be tilted or slid is provided in an opening provided in a roof of a vehicle, and the opening is opened and closed. Further, there is a slide type drive means for the sunroof panel, and in this slide type, a guide rail for slidably supporting the drive means is provided on the bottom wall of the sunroof frame provided at the lower part of the roof. It is fixed.

In a vehicle equipped with such a sunroof, the sunroof frame should be set so that the bottom surface of the drainage groove is one step lower than the fixed surface of the guide rail so as to prevent water from being flooded from the opening from adhering to the guide rail. A drainage groove formed by pressing on the side wall of a guide rail on the bottom wall is disclosed in, for example, Japanese Utility Model Publication No. 58-27851. By doing so, it is possible to prevent water from adhering to the guide rail.

However, in such a sunroof, the bottom of the drainage channel projects downward from the fixed surface of the guide rail on the bottom wall of the sunroof frame, so the ceiling surface on the indoor side is lowered by that amount. Has been
There is a problem that the head clearance is reduced.

Therefore, if a drain groove member formed of a member different from the sunroof frame is used, the drain groove member of the guide rail is arranged so that the bottom surface of the drain groove member and the fixed surface of the guide rail are at the same height. Can be placed laterally,
There is no need to make a drainage groove around the guide rail of the sunroof frame. Therefore, although it is possible to increase the head clearance by doing so, on the other hand, forming the drainage groove by a separate member causes a problem that the number of parts increases and the manufacturing process thereof becomes complicated.

<Problems to be Solved by the Invention> In view of the above-mentioned problems of the prior art, a main object of the present invention is to provide a drainage groove structure for a sunroof capable of expanding a head clearance and simplifying a manufacturing process. Especially.

<Means for Solving the Problems> According to the present invention, such an object is provided with an opening provided on the roof of a vehicle, a sunroof panel capable of opening and closing the opening, and below the roof. A sunroof frame having a sunroof frame and a drain groove provided in a bottom wall of the sunroof frame for receiving water from the opening and discharging the water, wherein the drain groove structure is the roof. A frame seal portion fixed to an end edge portion of a peripheral wall of the sunroof frame reaching the vicinity of the rear surface of the roof so as to close a space between the rear surface of the sunroof frame and the sunroof frame, and the peripheral wall from the fixed portion of the frame seal portion. A stretchable corrugated plate extending along the side surface on the opening side and having a stretchable corrugated shape, and a drainage channel continuously connected to the free end of the stretchable portion and having a substantially U-shaped cross section. On earth And a sunroof drainage structure.

<Operation> With this configuration, since the drain groove can be provided without making the bottom wall of the sunroof frame concave, the head clearance can be increased. Further, since the frame seal portion and the drain groove portion are integrally formed with each other through the stretchable portion having a stretchable corrugated plate shape, the height of the peripheral wall of the sunroof frame changes according to the shape of the back surface of the roof. Even in other words, that is, even if the intervals between the respective arrangement positions of the frame seal portion and the drain groove portion change, the frame seal portion and the drain groove portion can be suitably and easily mounted.
