GROMMET AND WIRE HARNESS WITH GROMMET
Document Type and Number:
WIPO Patent Application WO/2016/153045
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a grommet in which the deformation of the rear end accompanying the deformation of a tightening and securing part is suppressed, thereby improving the water-sealing performance thereof. [Solution] A grommet 40 is provided with: a rear band-mounting part 415 which is disposed apart from the rear end of the grommet and which secures an overlapping part of the grommet with a corrugated tube 5 fitted therein by tightening the overlapping part using a belt-like binding band 8; and multiple rear-end-side annular protrusions 411, a first securing-side annular protrusion 412, and a second securing-side annular protrusion 413 which protrude from the inner circumferential surface, extend in a circumferential direction and are arranged along the front-to-back direction X so as to engage with the protrusions and recesses of the corrugated tube 5. The grommet is constructed such that the rear-end-side annular protrusions 411 are disposed near the rear end, the first fixation-side annular protrusion 412 and the second fixation-side annular protrusion 413 are disposed on the inner surface of the rear band-mounting part 415 with a predetermined distance between each other, and a high deformation absorption part 414 with higher deformation-absorbing performance than the rear band-mounting part 415 is disposed between the rear-end-side annular protrusions 411 and the first securing-side annular protrusion 412.
