Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0021] Such as figure 1 As shown in -3, the grommet 1 of the embodiment includes: a cylindrical inner grommet 3; Outer grommet2.

[0022] The outer grommet 2 includes: an electric wire insertion cylinder 10 formed integrally with soft material and through which electric wires are inserted; the flange portion 12; and the annular lip portion 14 extending from the flange portion 12 and closely abutting against the opening edge of the mounting hole 6.

[0023] The wire insertion tube 10 is formed with a plurality of (two in the embodiment) substantially cylindrical tubes. An elliptical flange portion 12 is formed on one end side of these cylindrical portions. These cylindrical portions are formed by reducing the diameter from the flange portion 12 side. In this way, the flange portion 12 is integrally formed with the wire insertion tube portion 10 .

Abstract

This grommet (1) is designed for insertion into a mounting hole (6) of a panel (4), and is provided with a grommet inner (3) and with a grommet outer (2) assembled thereto so as to cover the grommet inner (3). The grommet outer (2) is provided with: an electrical cable insertion tube (10) through which an electrical cable is inserted; a flange (12) integrally formed with the electrical cable insertion tube (10) and positioned facing the opening edge (8) of the mounting hole (6); and an annular lip (14) extending from the flange (12) and positioned in close abutment against the opening edge (8). The annular lip (14) is furnished with a pressing part (34) for pressing the annular lip (14) against the opening edge (8) of the mounting hole (6), when the grommet inner (3) and the grommet outer (2) in the assembled state have been inserted into the mounting hole (6) and the flange (12) and the annular lip (14) urged into abutment.

Description

technical field [0001] The present invention relates to a grommet that is attached to a through hole provided in a panel to prevent water from around an electric wire inserted through the through hole. Background technique [0002] Many electronic components are mounted on an automobile, and many electric wires are routed from an engine room or the like of the vehicle to a vehicle compartment in order to control or activate the electronic components. The electric wires routed from the engine room or the like to the vehicle compartment are prevented from entering the vehicle compartment by rainwater or the like by using grommets for inserting the electric wires through the panel. [0003] As a conventional example, Patent Document 1 proposes a grommet mounting structure in which the grommet is provided on the joint surface facing the mounting member such as a panel, and is pressed against the mounting member in a liquid-tight state, and the whole is ring-shaped. The sealing ...
