<P>PROBLEM TO BE SOLVED: To provide a weather strip provided with a fitting base part, and a hollow seal part integrally formed with the fitting base part, and capable of maintaining the sealability even when the hollow seal part of a die molded part of an olefin thermoplastic elastomer TPO is subjected to the secular permanent set. <P>SOLUTION: The weather strip has a fitting base part 7 and a hollow seal part 13 integrally formed with the fitting base part 7. The seal part 13 is projected by the amount δ more than a conventional seal part, and increased in thickness accordingly. Thus, the seal lip amount of the similar degree to the conventional value is ensured even when the seal part is subjected to the secular permanent set. <P>COPYRIGHT: (C)2009,JPO&INPIT |
