端より上方へ突出している。FIG. 3 shows a cross-sectional view of a weather strip used by being attached to a flange of a trunk of an automobile. A hollow seal portion 12 made of sponge rubber is protruded from above. A seal lip 17 made of sponge rubber that extends diagonally 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 pairs of upper and lower clamping lips 13. 14.1
5.16 is provided. The thickness of these four clamping lips is almost the same, but the lower clamping lip 15 on the side of the sealing lip 17 and the upper clamping lip 14 on the side opposite to the sealing lip 17 are clamping lips 13.1 whose rising angles are opposite to each other.
For example, the gripping lips 14 and 1
The rising angles θ2 and 03 with respect to the horizontal of 5 are approximately 35 degrees, and the rising angles θ of the holding lips 13 and 16 with respect to the horizontal are approximately 35 degrees.
1 and θ◆ are set to about 20 degrees. Furthermore, 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 R of the base of the clamping lip) are different from the opposite clamping lip 16.13.
The length of the clamping lip 14.15 is set slightly lower than the mounting position of the clamping lip 14.15 on the opposite side.
It is set a little longer than the length of 16, and the gripping lip is 14゜1.
The tips of the grippers 5 project upwardly from the tips of the opposing clamping lips 13 and 16, respectively.

ことができる。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 flange portion 8 of the trunk of an automobile. The force of tilting toward the anti-seal lip side caused by this is received by the opposite clamping lip 13, 16 with a smaller rising angle, so that each of the two pairs of clamping lips does not bend to an extreme degree, that is, the mounting of the clamping part 11 is prevented. The weatherstrip is installed in the correct position without being tilted with respect to the flange portion 18, and the sealing performance of the seal lip 17 is also maintained well. FIG. It is a graph showing the change in insertion force with respect to the thickness of the flange part when the insertion force (force to fit the clamping part into the flange part) is measured when the weather strip shown in the figure is installed, and curve A is the weather strip of the present invention. Curve B shows the conventional weatherstrip of FIG. 1, and curve C shows the conventional weatherstrip of FIG. From this graph, it can be seen that in the weatherstrip of the present invention, the rising angle of the clamping lips 14 and 15 becomes large, and the clamping lip 14.
It can be seen that since the deformation stress of 15 is reduced, the insertion force (fitting force) is smaller throughout the entire plate thickness compared to the conventional one, and installation can be easily performed without increasing insertion resistance.

This is a graph showing changes, where the curve shows the weatherstrip of the present invention, the curve E shows the conventional weatherstrip shown in FIG. 1, and the curve F shows the conventional weatherstrip shown in FIG. 2. From this graph.

頼性が良好となる。In the weather strip of the present invention, the clamping lips 14 and 15
Although the rising angle of the clamping lips 14 and 1
5 is longer than the other clamping lips 13 and 16,
In particular, since the tip of the gripping lip protrudes upward from the opposing gripping lip, the reaction force of the gripping lip that the flange portion 18 receives increases, and the pulling and holding force increases throughout the entire plate thickness compared to the conventional one. The attachment reliability of the strip is improved.

, and the tips of the clamping lips 25 and 26 are approximately at the same height. Similarly to the weatherstrip shown in FIG. 3, the weatherstrip 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.

せることができる<Effects of the Invention> As explained above, according to the weather strip of the present invention, since the rising angle of the lower clamping lip on the seal lip side and the upper clamping lip on the side opposite to the seal lip is made larger than that of the opposing clamping lip, It is possible to prevent the weatherstrip from collapsing when it is attached due to the recoil force of the seal lip, etc., to ensure good sealing performance of the seal lip, and to reduce the insertion resistance of the flange part into the clamping part when it is attached. It is small and easy to assemble at the corners of flange parts or in thick-walled areas. Furthermore, if the gripping lip is made longer so that the tip of the gripping lip protrudes beyond the tip of the opposing gripping lip, the pulling and holding force in the installed state will be increased compared to conventional gripping lips, and the installation reliability can be improved. can
