Abstract
A grommet is provided with an elastic grommet body, a mounting groove, a seal material and a cover portion. The grommet body has a first cylindrical portion disposed at one side, a second cylindrical portion disposed at the other end and a third cylindrical portion disposed within the first cylindrical portion. The first cylindrical portion has a maximum inner diameter larger than a maximum inner diameter of the second cylindrical portion. The third cylindrical portion projects to the one side from an inner peripheral surface of the first cylindrical portion. The inner peripheral surface of the second cylindrical portion and the inner peripheral surface of the third cylindrical portion defines a harness insertion portion in which a wire harness is inserted from one side to the other side. The inner peripheral surface of the first cylindrical portion and the outer peripheral surface of the third cylindrical portion defines an annular space for allowing the first cylindrical portion to elastically deform. The mounting groove is annually formed on the outer peripheral surface of the first cylindrical portion. The seal material is filled in the harness insertion portion in a state that the wire harness is inserted. The cover portion is disposed in an end portion of one side of the grommet body and closes the annular space without affecting an elastic deformation of the first cylindrical portion. The grommet can be easily mounted by the closed annular space, and a sound prevention performance can be improved.
