Abstract
A grommet has an engagement tube with an elliptical cross-section and is provided continuous with and bent from a leading end of a narrow tube through which the wire harness passes while coming into close contact therewith. An annular vehicle body engagement recess is provided in an outer circumferential surface of the engagement tube. Arc-side reinforcements protrude radially inward at connecting positions between a circumferential wall of the narrow tube and arc-shaped circumferential walls of the engagement tube that face each other in a major axis direction. The thickness of the arc-side reinforcements is greater than the thickness of connecting positions between the circumferential wall of the narrow tube and respective linear circumferential walls that face each other in a minor axis direction.
Claims13
A grommet that is externally fitted to a wire harness and placed in a through hole formed in a vehicle body panel, the grommet being made of a rubber or an elastomer,
- wherein an engagement tube portion having an elliptical cross-sectional shape is provided so as to be continuous with and bent from a leading end of a narrow tube portion through which the wire harness passes while coming into close contact with the narrow tube portion,
- an annular vehicle body engagement recess is provided in an outer circumferential surface of a circumferential wall of the engagement tube portion, and
- arc-side reinforcement portions protruding in an inward radial direction are provided at respective connecting positions between a circumferential wall of the narrow tube portion and arc-shaped circumferential walls of the engagement tube portion that face each other in a major axis direction, and a thickness of the arc-side reinforcement portions is set to be greater than a thickness of connecting positions between the circumferential wall of the narrow tube portion and respective linear circumferential walls that face each other in a minor axis direction.
