## Abstract

A wire harness waterproofing structure includes a grommet that includes a pipe-formed body part the periphery of which is watertightly attached to a through hole which is bored in a body panel which separates a compartment outside part and a compartment inside part, and a small diameter tubular part one end of which is connected to the pipe-formed body part, a wire harness that includes a plurality of electric wires inserted through the tubular part in an unbound state and is wired with a predetermined height difference relative to the through hole, a diameter-increased part that are provided on at least one of the electric wires to forms a gap between the electric wires adjacent to the one of the electric wires.

## Claims

### Claim 1

A wire harness waterproofing structure comprising:
a grommet that includes:
a pipe-formed body part a periphery of which is watertightly attached to a through hole which is bored in a body panel which separates a compartment outside part and a compartment inside part; and
a small diameter tubular part one end of which is connected to the pipe-formed body part;
a wire harness that includes a plurality of electric wires inserted through the tubular part in an unbound state and is wired with a predetermined height difference relative to the through hole; and
a diameter-increased part that are provided on at least one of the electric wires to forms a gap between the electric wires adjacent to the one of the electric wires.

### Claim 2 (depends on 1)

The wire harness waterproofing structure according to claim 1,
wherein the one of the electric wires has the largest outer diameter among the plurality of electric wires.

### Claim 3 (depends on 2)

The wire harness waterproofing structure according to claim 2,
wherein the wire harness includes a plurality of electric wires having outer diameters different from each other, and
the diameter-increased parts that are provided on all of the electric wires having an outer diameter that is equal to or larger than a predetermined diameter determined in accordance with the predetermined height difference.

### Claim 4 (depends on 2)

The wire harness waterproofing structure according to claim 2,
wherein the wire harness includes a plurality of electric wire having the same outer diameter as each other, and
the diameter-increased parts that are provided on all of the electric wires having an outer diameter that is equal to or larger than a predetermined diameter determined in accordance with the predetermined height difference.
