Abstract
Official abstract text for this publication.
A wire-harness grommet that is not easily dislodged from a plate while minimizing the increase in its weight and cost is provided. In a grommet, a small-diameter cylindrical portion is connected to a connecting portion and can be bound at its ends to a member penetrating an interior of the small-diameter cylindrical portion. A large-diameter cylindrical portion includes an oblique reduced-diameter portion extending fully circumferentially and obliquely inward from where it is connected to the connecting portion. The small-diameter cylindrical portion includes a deformation limiting portion that protrudes farther than other parts of the small-diameter cylindrical portion so as to oppose the oblique reduced-diameter portion. The deformation limiting portion limits the range of inward deformation of the oblique reduced-diameter portion.
First claim
Opening claim text (preview).
What is claimed is: 1 . A grommet having an elastic member comprising: a large-diameter cylindrical portion having an annular recess formed therein into which a rim of a hole in a plate can be fitted, a connecting portion extending fully circumferentially and further inward from an inner surface of the large-diameter cylindrical portion, and a small-diameter cylindrical portion connected to the connecting portion and capable of being bound at its ends to a member that penetrates an interior of the small-diameter cylindrical portion, wherein the large-diameter cylindrical portion includes an oblique reduced-diameter portion extending fully circumferentially and obliquely inward from where the large-diameter cylindrical portion is connected to the connecting portion, and wherein the small-diameter cylindrical portion includes a deformation limiting portion that protrudes farther than other parts of the small-diameter cylindrical portion to oppose the oblique reduced-diameter portion such that the deformation limiting portion limits the range of inward deformation of the oblique reduced-diameter portion. 2 . The grommet according to claim 1 , wherein a plurality of the deformation limiting portions are formed side by side at intervals around the periphery of the small-diameter cylindrical portion. 3 . The grommet according to claim 1 , wherein the small-diameter cylindrical portion comprises: an inner small-diameter cylindrical portion connected to an innermost part of the connecting portion, and an outer small-diameter cylindrical portion formed outside of the inner small-diameter cylindrical portion so as to be connected to a part of the connecting portion closer to the large-diameter cylindrical portion than the part of the connecting portion connected to the inner small-diameter cylindrical portion, wherein the deformation limiting portion is formed on the outer small-diameter cylindrical portion. 4 . The grommet according to claim 2 , wherein the small-diameter cylindrical portion comprises: an inner small-diameter cylindrical portion connected to an innermost part of the connecting portion, and an outer small-diameter cylindrical portion formed outside of the inner small-diameter cylindrical portion so as to be connected to a part of the connecting portion closer to the large-diameter cylindrical portion than the part of the connecting portion connected to the inner small-diameter cylindrical portion, wherein the deformation limiting portions are formed on the outer small-diameter cylindrical portion. 5 . A wire harness comprising a bundle of electric wires and a grommet mounted on the bundle of electric wires, the grommet having an elastic member comprising: a large-diameter cylindrical portion having an annular recess formed therein into which a rim of a hole in a plate can be fitted, a connecting portion extending fully circumferentially and further inward from an inner surface of the large-diameter cylindrical portion, and a small-diameter cylindrical portion connected to the connecting portion and capable of being bound at its ends to the bundle of electric wires penetrating an interior of the small-diameter cylindrical portion, wherein the large-diameter cylindrical portion includes an oblique reduced-diameter portion extending fully circumferentially and obliquely inward from where the large-diameter cylindrical portion is connected to the connecting portion, and wherein the small-diameter cylindrical portion includes a deformation limiting portion that protrudes farther than other parts of the small-diameter cylindrical portion to oppose the oblique reduced-diameter portion such that the deformation limiting portion limits the range of inward deformation of the oblique reduced-diameter portion.
