<P>PROBLEM TO BE SOLVED: To provide a structure of a weather-strip for preventing permanent setting and a crack of a notch part in advance by improving a structure of a hollow seal lip, especially a structure in a nearest position of the notch part formed on an inner wall surface of the seal lip. <P>SOLUTION: An upper notch 12 is formed on the inner wall surface of the seal lip 4. A projection 18 is integrally formed of high hardness rubber on the nearest position of the upper notch 12 out of the inner wall surface 14 of a circular inner wall part 10 and the inner wall surface 15 of an inclined wall part positioned on both sides with the upper notch 12 sandwiched. When the seal lip 4 is collapsed and deformed with the upper notch 12 as a starting point, a tip end surface 18a of the projection 18 is in elastically contact with the inner wall surface 14 instead of the inner wall surface 15 to prevent the inner wall surface 14 and the inner wall surface 15 from directly contacting elastically with each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
