<P>PROBLEM TO BE SOLVED: To provide a seal member which can exhibit sealing performance equivalent to a conventional one using adhesive by keeping adhesion between an insert member and a rubber section without using the adhesive. <P>SOLUTION: A seal member 1 is formed by integrally molding an insert member 10 and a rubber section 20 including the insert member 10, and makes a part of the rubber section 20 function as seal lips 21, 22. Furthermore, in the insert member 10, an annular engaging groove 13 is arranged as a concavity engaging the part of the rubber section 20 at the time of integrally molding. Therefore, the adhesion between the insert member 10 and the rubber section 20 can be improved by an anchor effect based on engagement between the annular engaging groove 13 of the insert member 10 and the part of the rubber section 20. <P>COPYRIGHT: (C)2009,JPO&INPIT |
