つた。<Prior art> This weather strip is used as a weather strip to be attached to the trunk or door of an automobile, and has a holding part 1 with an inverted U-shaped cross section in which an insert is embedded, and a hollow seal part 2 made of sponge rubber is provided on the top of this holding part 1. Two pairs of upper and lower clamping lips 3, 4, 5, 6 are provided inside the clamping part 1.
A weather strip is used in which a seal lip 7 made of sponge rubber is provided on the outer lower part of one side of the holding part 1. This type of weather strip is used, for example, in the trunk of a car, as shown in FIG. When attached to the flange portion 8, the trunk door 9 will close due to the repulsion force of the seal lip 7.
This caused the problem that the sealing properties of the seal lip 7 deteriorated, causing water leakage.

た。 For this reason, as shown in FIG.
A weather strip that was thicker than the previous one was developed (see Japanese Utility Model Publication No. 48916/1983). however,
Although such a weather strip can prevent the weather strip from falling inward when it is attached to the flange of the trunk, the insertion resistance when inserting the flange into the holding part 1 increases, and in particular, the sheet metal of the flange is damaged. Assembling workability at double thick parts and corner parts deteriorated, and it took time and effort to fit the weather strip holding part 1 into the flange part, and there was a risk that the fitting would be incomplete.

より上方へ突出している。 FIG. 3 shows a cross-sectional view of a weather strip that is used by being attached to the flange of a car trunk. Hollow seal part 12 made of sponge rubber
is installed protrudingly. A seal lip 17 made of sponge rubber that extends obliquely downward is provided on the lower outer side of one side of the clamping part 11, and inside the clamping part 11, which has an inverted U-shaped cross section, there are two opposing pairs of upper and lower clamping lips 13,
14, 15, and 16 are provided. The thickness of these four clamping lips is almost the same, but the lower clamping lip 15 on the sealing lip 17 side and the upper clamping lip 14 on the side opposite to the sealing lip 17 have a rising angle compared to the opposing clamping lips 13 and 15. For example, the rising angles θ 2 and θ 3 of the clamping lips 14 and 15 with respect to the horizontal are set to about 35 degrees, and the rising angle θ 1 of the clamping lips 13 and 16 with respect to the horizontal is set to approximately 35 degrees.
and θ 4 are set to approximately 20 degrees. Also, the mounting positions of the lower clamping lip 15 on the side of the seal lip 17 and the upper clamping lip 14 on the side opposite to the sealing lip (horizontal position of the base of the clamping lip) are slightly smaller than the mounting positions of the clamping lips 16 and 13 on the opposite side. Further, the lengths of the clamping lips 14, 15 are set to be slightly longer than the lengths of the clamping lips 13, 16 on the opposite side, and the tips of the clamping lips 14, 15 are set to be slightly longer than the lengths of the clamping lips 13, 16 on the opposite side. It protrudes upward from the tip.

れる。 The weather strip configured in this manner is attached to the flange portion 8 of the trunk of a car, for example, by fitting its clamping portion 11 into the weather strip. The resulting tilting force toward the anti-seal lip side is received by the opposite side clamping lips 13 and 16, which have a smaller rising angle. The weather strip is installed in a correct posture without being tilted with respect to the flange portion 18, and the sealing performance of the seal lip 17 is maintained well.

行なうことができる。 Figure 5 shows the relationship between the thickness of the flange part and the insertion force (force for fitting the clamping part into the flange part) when installing the weather strip of the present invention and the conventional weather strip shown in Figures 1 and 2. This is a graph showing changes in insertion force, where curve A is for the weatherstrip of the present invention, curve B is for the conventional weatherstrip shown in FIG. 1, and curve C is for the conventional weatherstrip shown in FIG.
The weather strip shown in the figure is shown. From this graph, it can be seen that in the weather strip of the present invention, the rising angle of the clamping lips 14 and 15 is increased, and the deformation stress of the clamping lips 14 and 15 during fitting is reduced, so the insertion force (fitting force) is lower than that of the conventional one. It can be seen that it becomes smaller throughout the entire plate thickness, and can be easily installed without increasing insertion resistance.

性が良好となる。 Furthermore, FIG. 6 shows the change in the holding force with respect to the thickness of the flange part when the pulling and holding force of the clamping part was measured in the installed state of the weatherstrip of the present invention and the conventional weatherstrip shown in FIGS. 1 and 2. In this graph, curve D shows the weather strip of the present invention, curve E shows the conventional weather strip of FIG. 1, and curve F shows the conventional weather strip of FIG. 2. From this graph,
In the weather strip of the present invention, the clamping lip 14
Although the rising angles of gripping lips 14 and 15 have become larger, the lengths of gripping lips 14 and 15 are longer than those of gripping lips 13 and 15.
The flange portion 18 is longer than the flange portion 6, and its tip protrudes upwardly from the opposing clamping lip.
It was found that the reaction force exerted by the clamping lip on the weather strip increases, and the pull-out and holding force increases throughout the entire plate thickness compared to the conventional one, and the installation reliability of the weather strip improves.

The tips of 26 are at almost the same height. Similarly to the weather strip shown in FIG. 3, the weather strip shown in FIG. It is possible to prevent the user from collapsing in such a situation. Further, the pulling and holding force changes as shown by curve G in the graph of FIG. 6, and performance almost equivalent to that of the conventional weather strip can be obtained.

Because of the formation,
It is possible to prevent the weather strip from collapsing when it is installed due to the repulsion force of the seal lip, and to ensure good sealing performance of the seal lip.In addition, the insertion resistance of the flange part into the clamping part during installation is small, and the flange part Improves assembly workability in corners and thick-walled areas. Moreover, compared to the conventional one, the pull-out retention force in the attached state is increased, and attachment reliability can be improved.
