PROBLEM TO BE SOLVED: To provide a grommet which allows for stabilization of waterproofness by a seal portion over the whole area in the circumferential direction, in a seal portion formed elliptically.SOLUTION: In a grommet 1 including an annular body 9 having a pair of linear portions 5, 5 attached to an attachment member 3 and facing each other, and a pair of arcuate portions 7, 7 for coupling both ends of the pair of linear portions 5, 5, respectively, and a seal portion 11 formed continuously so as to be able to deform elastically in the circumferential direction on the outer peripheral side of the body 9, and adhering to the surface of the attachment member 3, the seal portion 11 is set so that the rigidity increases gradually from the pair of linear portions 5, 5 side toward the pair of arcuate portions 7, 7 side.SELECTED DRAWING: Figure 2 |
