The problem that the sealing performance and appearance due to short-circuiting and floating are impaired is solved, and the first mounting base 3 is fixed to a predetermined position of the body panel 2 by the clip 6 and then adhered by the adhesive means 15 to thereby prevent the sticking deviation. Can be resolved. Moreover, even if the angle formed by the first mounting surface 2a and the second mounting surface 2b of the body panel changes, it can be dealt with by bending at the bent portion.

  According to the second aspect of the invention, the displacement of the mounting position of the mounting base can be eliminated by the movement of the projection 14 coming into contact with the body panel 2 during assembly. Although the number of the protrusions 14 described above may be one, a pair is preferably provided, and each of the protrusions 14 is individually in contact with the first mounting surface 2a and the second mounting surface 2b. Thereby, position shift can be prevented more reliably.

  The weather strip mounting structure of the embodiment of the present invention will be described below with reference to FIG. In the figure, the same reference numerals are given to the same structural portions as those of the mounting structure shown in FIGS.

  FIG. 5 shows an attachment structure of the weather strip 11 taken along the line A-A in FIG. 1, and the weather strip 11 attached to the periphery of the door opening of the automobile body is composed only of an extrusion forming portion having no mold forming portion. Alternatively, a portion corresponding to a part of the corner at the periphery of the door opening is constituted by a mold forming portion. The weather strip 11 includes a first attachment base 3 formed of solid rubber in an extrusion molding portion, and a hollow seal formed of sponge rubber having a specific gravity of 0.4 to 0.8, which is formed so as to protrude from the attachment base 3. 5, a second mounting base 12 made of the same material as the first mounting base 3, extending from the first mounting base 3 toward the inside of the door opening (upward in FIG. 5), and the mounting The seal lip 8 extends from the first mounting base 3 on the side opposite to the base 12 and is made of the same material as the hollow seal 5. The connecting portion connecting the first mounting base 3 and the second mounting base 12 is a bent portion with a notch 13 so that the second mounting base 12 can be bent with respect to the first mounting base 3. It has become. Protrusions 14 are formed on both sides of the bent portion. The first mounting base 3 is not limited to solid rubber, and can be formed from sponge rubber. Further, the notch 13, the pair of protrusions 14 and the like can be provided only in the extrusion molding part, and can be omitted from the molding part.
