It is an object of the present invention to provide such a weather strip that a noise is prevented from being caused as a window pane is moved up and down in contact with the strip. The weather strip 9 according to the present invention includes a base portion 11, a seal lip 12, and a seal portion 14 having an internal opening 13. The pane contact part 20 of the seal portion 14 is made larger in thickness than the pane non-contact part 21 thereof. The pane contact part 20 is bent at the bent portion 20a thereof. The surface R of the bent portion 20a, with which the window pane 8 comes into contact, is a curved surface nearly unchanged in radius of curvature. The strip 9 has a first groove 22 inside a first bend point 18, and a second groove 23 inside a second bend point 19. The second groove 23 is larger in depth but smaller in width than the first groove 22. When the window pane 8 is moved up and down in contact with the weather strip 9, the pane contact part 20 of the seal portion 14 is hardly deformed but swung up and down about the second bend point 19. The pane contact surface R of the bent portion 20a is so curved that the area of contact thereof with the pane 8 is nearly unchanged despite the vertical movement thereof. |
