摘要：PROBLEM TO BE SOLVED: To provide excellent water stop performance and reduce the required number of fastening belts in connecting portions of a grommet formed to have one cylindrical shape by interconnecting two cylindrical members each comprising an elastic material. SOLUTION: A grommet 1 includes: a first soft cylindrical member 10 and a second soft cylindrical member 20 each of which comprises an elastic material; and a hard cylindrical member 30 comprising a harder material. The hard cylindrical member 30 is covered with a first connecting portion 11 at one end of the first soft cylindrical member 10 while the inner peripheral face of the first connecting portion 11 is brought into close contact with the outer peripheral face of a first region 31 of the hard cylindrical member 30. The first connecting portion 11 is covered with a second connecting portion 21 at one end of the second soft cylindrical member 20 while the inner peripheral face of the second connecting portion 21 is brought into close contact with the outer peripheral face of the first connecting portion 11. The hard cylindrical member 30 is covered with a third connecting portion 22 continuing to the second connecting portion 21 in the second soft cylindrical member 20 while the inner peripheral face of the third connecting portion 22 is brought into close contact with the outer peripheral face of a second region 32 of the hard cylindrical member 30. A belt 91 is fastened by the second connecting portion 21. COPYRIGHT: (C)2013,JPO&INPIT
