Description

TECHNICAL FIELD The present invention relates to a sunroof frame structure for a sunroof. <Prior Art> A sunroof is known which has an opening provided on a roof of a vehicle and a sunroof panel capable of opening and closing the opening, and the sunroof panel can be tilted or slid. In a vehicle equipped with such a sunroof, a drainage groove is provided in the lower portion of the roof for guiding the infiltration of water from the opening to the outside of the vehicle. By the way, generally, for example, as disclosed in Japanese Utility Model Publication No. 58-27851, a sunroof frame is provided below the roof in order to fix the guide rails of the sunroof panel. Therefore, a recessed portion which is lowered by, for example, press working is provided in the peripheral portion of the bottom wall of the sunroof frame, and the recessed portion serves as a drainage groove. However, in such a sunroof, a tube or the like is connected to each corner of the sunroof frame and is provided so as to pass through the inside of the pillar of the vehicle so that the water in the drainage groove is drained to the outside of the vehicle. ing. Therefore, in order to connect a tube or the like, a pipe is fixed to the outer peripheral wall of each corner of the sunroof frame by brazing or the like. Therefore, it is necessary to take rust preventive measures on the brazed portion, which causes a problem that the manufacturing process becomes relatively complicated. Further, since the bottom of the drainage groove projects downward from the bottom wall of the sunroof frame, the ceiling surface on the indoor side is provided at a position lowered by the amount of projection, which reduces the head clearance. There is also a problem. <Problems to be Solved by the Invention> In view of the above-mentioned problems of the prior art, the main object of the present invention is to prevent the occurrence of rust on the sunroof frame and further increase the head clearance. To provide a frame structure. <Means for Solving the Problems> According to the present invention, such an object is to provide an opening provided on a roof of a vehicle, a sunroof panel capable of opening and closing the opening, and a portion provided below the roof. A sunroof frame structure having a sunroof frame and a drain groove for receiving and draining water from the opening at the peripheral edge of the sunroof frame, wherein the drain groove is the sunroof frame. A plurality of substantially linear portions formed by extruding a synthetic resin material so as to have a substantially U-shaped cross section made of separate members and extending along each linear portion of the peripheral portion of the sunroof frame; and the sunroof. The frame has a substantially same cross-sectional shape so as to correspond to the corners of the peripheral edge of the frame and to be continuous with the linear portion, and a drain tube for fitting the drain tube. This is achieved by forming the ren tube mounting portion by a corner member integrally formed. <Operation> In this way, it is possible to prevent water from directly contacting the sunroof frame, and by integrally forming the drain tube mounting portion on the corner member that constitutes the drainage groove, the drain tube mounting member is mounted on the sunroof frame. It is not necessary to fix the pipe as brazing. Further, since the bottom wall of the sunroof frame does not have to be recessed to form the drainage groove, it is possible to eliminate a portion of the sunroof frame that largely projects toward the indoor side due to the bottom wall. <Examples> Hereinafter, preferred examples of the present invention will be described in detail with reference to the accompanying drawings.

Fitted and drained 36
The water inside will flow to the drain tube 47 via the drain tube mounting portion 51, and the water will be drained without directly touching the sunroof frame 4. Further, another embodiment based on the present invention will be described below with reference to FIGS. 5 and 6. The parts corresponding to those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, for example, the drain groove member 52 made of synthetic resin is formed into a substantially U-shaped cross section by extrusion.
The side wall 34 of the outer peripheral wall 26 of the sunroof frame 4 and the bottom wall 24
And a side surface of the block portion 24 of the guide rail 6 are fixed to each other so as to form a drainage groove. The drain groove member 52 is provided in the straight portion of the sunroof frame 4, and at the corners of the sunroof frame 4,
As shown in FIG. 6, a drain tube mounting portion 51 integrally formed with a corner member formed in the same manner as the above embodiment.
The drain tube 47 is connected to. Also in this embodiment, since the drain groove is formed by the drain groove member 52 which is a separate member from the sunroof frame 4, it is necessary to form a recess in the bottom wall 24 of the sunroof frame 4 to form the drain groove. Instead, the bottom wall 23 of the sunroof frame 4 can be formed in a substantially flat shape. Although the frame seal 28 and the drain groove member 52 are integrally formed by extruding a synthetic resin material, they may be formed by extruding a metal such as an aluminum material. Further, in the above-mentioned embodiment, the injection-molded rubber molding member 50 is provided at the corner portion of the sunroof frame 4, but the invention is not limited to the rubber material. <Effects of the Invention> As described above, according to the present invention, since the drain groove is formed by the drain groove member which is a separate member from the sunroof frame, the sunroof frame is not directly contacted with water, so that the sunroof frame is coated. Can be simplified. Also, by integrally molding the drain tube mounting portion for draining water to the outside of the vehicle with the corner member of the drainage groove, it is not necessary to braze the drain pipe member to the sunroof frame, and with the same material, Since a continuous surface extending from the drainage groove to the drain tube mounting portion is formed, it is not necessary to perform a special rust-prevention treatment such as filling a clearance at the boundary, and the manufacturing cost can be reduced. Furthermore, since the drain groove can be formed without recessing the bottom wall of the sunroof frame, the bottom wall of the sunroof frame can be formed in a substantially flat shape, and the head clearance on the indoor side can be increased. The effect is extremely large.
