Abstract
A grommet includes: a first coupling portion that couples a first tubular portion and a first base portion to each other; and a second coupling portion that couples a second tubular portion and a second base portion to each other. The first coupling portion and the second coupling portion are provided with a space therebetween in the axial direction of the grommet. The first coupling portion includes a first flexible portion. The second coupling portion includes a second flexible portion. The first flexible portion and the second flexible portion are configured to bend so as to absorb an inclination of a wire harness with respect to a vehicle body panel. The first coupling portion and the second coupling portion provide a first sound insulation space therebetween.
Claims9
A grommet comprising:
- a main body that includes a seal portion configured to come into contact with a panel including an attachment hole to which the grommet is attached and through which a wire harness is passed;
- a tubular portion into which the wire harness is inserted, the tubular portion including a first tubular portion, a second tubular portion and a third tubular portion in contact with an outer circumferential surface of the first tubular portion;
- and
- a plurality of coupling portions that are provided with a space therebetween in an axial direction of the grommet, and that include a first coupling portion coupling the main body and the first tubular portion, a second coupling portion coupling the main body and the second tubular portion, and a third coupling portion coupling the main body and the third tubular portion,
- wherein at least one of the first, second and third coupling portions includes a flexible portion configured to bend so as to absorb an inclination of the wire harness with respect to the panel, and
- the first and second coupling portions provide a first sound insulation space therebetween, and the first and third coupling portions provide a second sound insulation space therebetween.
A grommet comprising:
- a main body that includes a seal portion configured to come into contact with a panel including an attachment hole to which the grommet is attached and through which a wire harness is passed;
- a tubular portion into which the wire harness is inserted;
- and
- a pair of coupling portions that are provided with a space therebetween in an axial direction of the grommet, and that each of the pair of coupling portions couple the main body and the tubular portion to each other,
- wherein at least one of the pair of coupling portions includes a flexible portion configured to bend so as to absorb an inclination of the wire harness with respect to the panel,
- the pair of coupling portions provide a sound insulation space therebetween,
- the main body includes a first member that is coupled to the tubular portion by one of the pair of coupling portions, and a second member that is coupled to the tubular portion by an other of the pair of coupling portions,
- the first member includes the seal portion,
- the second member includes a covering portion configured to cover an insertion hole of a sound insulation member provided on one side surface of the panel, and
- the flexible portion is provided at least in the other coupling portion that couples the second member to the tubular portion.
