施例の主たる相違は、磁性スポンジゴム部の形成部位の
相違である。81 Next, examples will be explained based on each nursery school. The main difference between each embodiment is the difference in the location where the magnetic sponge rubber portion is formed.

のシール性に与える影響は少ない。(1) Fig. 1... The door is attached to the abutting surface of the hollow seal part 3 of the mold weather strip, and the mounting sash of the base 1 is attached to the magnetic sponge rubber part 5.7 with a predetermined width only on the surface layer. It is said that In this embodiment, the main body portion and the magnetic sponge rubber portion forming portion are simultaneously molded and vulcanized by two-color extrusion, and then magnetized to form the magnetic sponge rubber portion. Further, in this embodiment, since the thickness of the magnetic sponge rubber portion is usually small, one filled with a high amount of magnetic material is used (for example, Examples 5 and 6 in Table 2). In this case, even if the hardness of the magnetic rubber is high, since it is thin, it will have little effect on the sealing performance of the hollow seal portion.

なる。In addition, as in these embodiments, by using the magnetic sponge rubber portion 7 as the abutting portion of the mounting sash, the sealing performance between the mounting sash 12 and the mounting base 1 is improved. Moreover, solid magnetic rubber parts may be used instead of the magnetic sponge rubber parts 7, and they may be arranged at a predetermined pitch. In this case, it is possible to reduce the number of attachment means such as clips normally provided on the base 1.

In this embodiment, the wall thickness of the magnetic sponge rubber portion 5A can be increased, and a large magnetic force can be obtained. Therefore, it is possible to use a formulation that is not highly filled with magnetic material and has a small surface hardness (for example, , Table 2 Examples 3 and 4).

Further, the body flange abutting portion of the body flange holding lip 8.8 is a magnetic sponge rubber portion 10. This improves the sealing performance between the body flange portion and the clamping lip.

As shown in the above example, the seal lip portion 3C may also be partially or entirely made up of a magnetic sponge rubber portion 5D.
この場合は、車体板金面に対するシール性が向上する。In this case, the sealing performance against the vehicle body sheet metal surface is improved.
