## Abstract

A connecting end portion of a shield pipe with respect to a shield member is waterproofed. A shield conduction path includes: a shield pipe having a connecting end portion opened obliquely downward; a braided wire fasten to an outer periphery of the portion by a swaging ring; a plurality of wires inserted into the pipe and braided wire; a rubber shield grommet and surrounding a fastening region between the braided wire and swaging ring; a binding band that fixes an upper end portion of the grommet to an outer periphery of the pipe in a liquid tight manner; a tube formed of synthetic resin surrounding the braided wire and having an upper end portion surrounding a lower end of the grommet; and exterior adhesive tape wound in a liquid tight manner from an outer periphery of the upper end portion of the tube over an outer periphery of the grommet.

## Claims

### Claim 1

A shield conduction path comprising:
a shield pipe having one end portion formed as a connecting end portion, the connecting end portion being opened obliquely downward;
a shield member having a cylindrical shape and flexibility, the shield member being fasten to an outer periphery of the connecting end portion in a conductive manner by a swaging ring;
a plurality of wires inserted into the shield pipe and the shield member;
a shield grommet formed of rubber, the shield grommet being arranged so as to surround at least a fastening region between the shield member and the swaging ring;
a fixing member that fixes an upper end portion of the shield grommet to an outer periphery of the shield pipe in a liquid tight manner;
a tube having flexibility and formed of synthetic resin, the tube surrounding the shield member and being arranged such that an upper end portion of the tube surrounds at least a lower end portion of the shield grommet; and
an adhesive tape wound in a liquid tight manner from an outer periphery of the upper end portion of the tube over an outer periphery of the shield grommet.

### Claim 2 (depends on 1)

The shield conduction path according to claim 1, wherein the adhesive tape is wound downward from the shield grommet toward the tube in a spiral manner.

### Claim 3 (depends on 2)

The shield conduction path according to claim 2, further comprising a pipe grommet formed with a wire sealing portion through which the wires are caused to penetrate individually in a liquid tight manner and formed with a pipe sealing portion that seals an opening of a lower end of the shield pipe in a liquid tight manner.

### Claim 4 (depends on 1)

The shield conduction path according to claim 1, further comprising a pipe grommet formed with a wire sealing portion through which the wires are caused to penetrate individually in a liquid tight manner and formed with a pipe sealing portion that seals an opening of a lower end of the shield pipe in a liquid tight manner.

### Claim 5 (depends on 1)

The shield conduction path according to claim 1, wherein the lower end portion of the shield grommet is located at a height position corresponding to the connecting end portion of the shield pipe in an axial line direction of the shield pipe.
