2. Description of the Related Art In passenger compartments of vehicles such as passenger cars,
Various vehicle interior members are mounted for the purpose of improving the texture of the passenger compartment. For example, the roof member to be mounted on the roof portion in the passenger compartment is a sheet-like member that is made of resin or fabric having flexibility and is attached to the roof portion, which has been used in the past. It was said to be a member of. However, a roof member that has been implemented in recent years is preformed to have an outer shape that matches the overall shape of the roof portion as illustrated in FIG. 7, and the roof member is easily assembled and attached to the roof portion. It is referred to as panel 10.

As shown in FIGS. 8 and 9, the roof panel 10 includes a base material 12 having a laminated structure in which glass fibers 16, 16 are adhered on both sides of a plate-shaped foam core material 14, and a base material 12 for the base material. The outer surface 18 of the material 12 (the surface facing the passenger compartment) 12a is covered with a skin material 18. The roof panel 10 is formed based on a press forming technique. The base material 12 supplied as a flat plate-like material is formed into an uneven shape that matches the overall shape of the roof portion, and at the time of this forming step. The outer surface 12a of the base material 12 is coated with the skin material 18 at the same time. The base material 1
2 has a thickness of 2 though there is some variation from site to site
The foamed core material 1 having a size of about 4 mm and hot-pressed while being impregnated with a urethane-based adhesive and molded into the above-described shape
The weight is reduced and the shape is maintained by 4.
The glass fiber 1 adhered to both outer surfaces of the foamed core material 14.
6 and 16 improve the rigidity of the outer surface portion. The skin material 18 is made of synthetic resin, woven fabric typified by fabric, knit, or moquette, and has flexibility, and is exposed to the passenger compartment to improve the texture of the roof panel 10. Is.

On the other hand, in vehicles such as passenger cars, it is possible to provide an opening window in the roof portion according to the taste of the user. Generally, the roof portion provided with such an opening window is referred to as a "sunroof". Or "moon roof". In the roof panel 10 implemented in a vehicle provided with such an opening window, as shown in FIG. 7, a portion corresponding to the opening window is formed into a convex shape, and a cut line CL is formed in a later step. It is necessary to open the opening 22 aligned with the opening window by cutting the unnecessary portion 20 by making a cut along (FIG. 8).

Here, the opening 22 is formed, for example, by the method illustrated in FIG. That is, after the base material 12 is molded as described above and the outer surface 12a of the base material 12 is coated with the skin material 18, only a portion of the skin material 18 near the cut line CL is peeled from the base material 12. The opening 22 is formed by inserting the cutting edge of the cutting tool 24 such as a cutter from the lateral outside along the cut line CL to make a cut, thereby cutting off the unnecessary portion 20. Then, the base material end portion 26 obtained when the base material 12 is cut by the cutting tool 24 is obtained by winding and adhering the skin end 28 of the skin material 18 onto the back outer surface 12b of the base material 12. The surface end 28 is covered so as not to be exposed to the opening 22 (FIG. 10).

[0006]

However, the substrate end portion 26 obtained by inserting the cutting tool 24 has an uneven surface or a protrusion such as a burr on the edge in the thickness direction. 30 is easily formed. Therefore, in the end structure in which the skin end 28 of the skin material 18 is directly and closely wound around the base end 26, the presence of the protrusions 30 such as burrs appears on the skin end 28. However, there is an inherent problem that the texture and texture are deteriorated (FIG. 10). In particular, since the base material 12 has a laminated structure in which the glass fibers 16 are adhered on both sides of the foamed core material 14, a convex portion 30 composed of an edge of the glass fiber 16 is easily formed at the base material end portion 26. In addition to the tendency, when the cutting edge of the cutting tool 24 is worn and the cutting performance is deteriorated, this tendency becomes more remarkable. In addition, the substrate 1 using a plurality of cutting tools 24
When making a cut in 2, a step due to an attachment error of each cutting tool 24 or the like is formed in the base material end portion 26, and in this case also, the presence of the step appears in the skin terminal 28 as it is. I will end up.

In addition to the end structure for winding the skin end 28 of the skin material 18, for example, as shown in FIG. 11, a molding member 34 separately molded into a substantially U-shaped cross section is used as a base material end. An end structure in which the base member end 26 is covered by being mounted on the part 26 is also implemented. However, in such an end structure, the molding member 34 is exposed at the outer peripheral edge of the opening 22, so that the appearance eventually becomes unsatisfactory, and the problem of texture deterioration cannot be solved satisfactorily. .
