時には、第６図に示すように取付基部８とシール基部９
とが略直線状に並んだ断面形状に成形される。Since the end 1a of the hemming portion of the hood l extends below the sealing member mounting surface of the hood inner panel 3, in order to arrange the sealing member 4 along the shape, the mounting base 8 and the seal base 9,
A notch portion 11 is formed. This notch portion 11 is
A recess is formed in the lower surface in the attached state, and by partially thinning the notch portion 11, the seal base 9, that is, the entire hollow seal portion 10 can be bent relative to the mounting base 8. Incidentally, during extrusion molding, the seal member 4 has a mounting base 8 and a seal base 9, as shown in FIG.
It is formed into a cross-sectional shape in which the and are lined up in a substantially straight line.

質に欠けるという不具合がある。Problems to be Solved by the Invention In the above configuration, if the size of the notch portion 11 is large to a certain extent, the seal base portion 9 easily bends with respect to the mounting base portion 8. There is a problem in that the product quality is deteriorated because the material hangs downward, or as shown in FIG. 7, it loses its rigidity when touched with fingers or the like.

。Furthermore, if the size of the notch portion 11 is made small to obtain a sufficient sense of rigidity, it becomes difficult to bend at the notch portion 11.
The bending state will be different between the part fixed by the resin clip 7 and the part intermediate between the fixing points. In other words, even if the notch portion 11 is relatively difficult to bend, the resin clip 7
If the mounting base 8 is firmly fixed to the panel surface, the fifth
As shown in the figure, the mounting base 8 and seal base 9 are bent along the shape of the tip of the hood 1, but the resin clip 7
If the intermediate portion is not fixed, the mounting base 8 will float up as shown in FIG. 8, and the lower end of the hollow seal portion 10 will accordingly protrude forward. Therefore, when looking at the seal member 4 as a whole, the hollow seal portion IO becomes wavy back and forth, deteriorating the external appearance.
