Abstract

A grommet arranged between a pipe and an outer cover that surrounds a braided member connected to the pipe, the grommet including a body with a pass-through space through which a caulking portion of a caulking ring for caulking the braided member to an end portion of the pipe can move in an axial direction.

First claim

The invention claimed is:

1. A grommet arranged between a pipe and an outer cover that surrounds a braided member connected to the pipe, the grommet comprising
a body with a first end portion, a second end portion and a protruding portion between the first end portion and the second end portion,
wherein the protruding portion is provided with a pass-through space through which a caulking portion of a caulking ring for caulking the braided member to an end portion of the pipe can move in an axial direction,
wherein a radial dimension of both the first end portion and the second end portion is smaller than a radial dimension of the caulking portion, and a radial dimension of the pass-through space of the protruding portion along an entire axial length between a first end and a second end of the protruding portion is greater than the radial dimension of the caulking portion,
wherein an axial dimension of the protruding portion is larger than an axial dimension of the first end portion and the second end portion,
wherein the protruding portion includes an accordion in which peaks and valleys are provided alternatingly and continuously in the axial direction,
wherein the accordion is provided only at an intermediate portion halfway between the first end and the second end of the protruding portion and not along the entire axial length of the protruding portion between the first end and the second end.

2. The grommet according to claim 1 , wherein the pass-through space is provided inside of a protrusion formed protruding from a main body portion of the body to an outer side in a radial direction, and a width of the protrusion is different on a pipe side and on an outer cover component side.

3. A wire harness comprising:
the pipe;
the braided member connected to the pipe;
the caulking ring for caulking the braided member to the end portion of the pipe;
the outer cover that surrounds the braided member; and
the grommet according to claim 1 .

4. The wire harness according to claim 1 , wherein the caulking ring is located axially between the accordion and the end of the body.

5. The wire harness according to claim 1 , wherein the first end and the second end of the protruding portion limit movement of the caulking portion in the axial direction.
