Abstract

A vehicle wiring structure equipped with a pipe (20), the two ends of which are inserted into the vehicle through an electrical-load-side through-hole and a power-source-side through-hole provided in the floor, and power cables (40a, 40b, 41), which are inserted in the pipe (20) and connect a power source and electrical loads. The power cables pulled out of the end part of the pipe (20) inserted through the power-source-side through-hole (60) are restrained by a first cable guide (70) provided inside the vehicle and are wired to a power source connection part, while the end part of the pipe (20) inserted through the power-source-side through-hole (60) reaches as far as the position where the first cable guide (70) is provided. The pipe (20) is supported by a through-hole seal member (61) that has a pipe through-hole (62) through which the pipe (20) passes and that closes the power-source-side through-hole (60).

Claims

1. A vehicle wiring structure which uses a power cable to connect between a power source and an electrical load device disposed inside a vehicle with a space therebetween in a vehicle front-to-back direction, comprising;

a pipe disposed under a floor of the vehicle between a position below where the power source is installed and a position below where the electrical load device is installed, and having opposite ends thereof inserted into the vehicle via a power-source-side through-hole and an electrical-load-side through-hole provided in the floor;

a power cable inserted through the pipe connecting the power source and the electrical load device;

a first cable guide provided inside the vehicle restraining the power cable adjacent the end of the pipe inserted through the power-source-side through-hole, the power cable being wired to a connection part of the power source, and the end of the pipe inserted through the power-source-side through-hole extending to the first cable guide; and

a through-hole seal member having a pipe through-hole through which the pipe passes and supporting the pipe, the seal member closing the power-source-side through-hole.

2. The vehicle wiring structure according to claim 1, wherein the pipe through-hole of the through-hole seal member is formed of a seal resin, and the pipe is supported by the seal resin.

3. The vehicle wiring structure according to claim 2, wherein the pipe through-hole includes a grommet protecting the power cable from an edge of the end of the pipe.

4. The vehicle wiring structure according to claim 1, wherein a center of the pipe through-hole of the through-hole seal member is not the same as a center of a closing part of the power-source-side through-hole.

5. The vehicle wiring structure according to claim 1, wherein the pipe is made from metal and is grounded to a body of the vehicle.

6. The vehicle wiring structure according to claim 1, wherein the power-source-side through-hole and the connection part of the power source are disposed with a space therebetween in a vehicle right-to-left direction, and

wherein a second cable guide bends the power cable protruding from the first cable guide in the vehicle front-to-back direction, to a direction toward the connection part of the power source.
