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 disposed inside a vehicle with a space therebetween in a vehicle front-to-back direction, comprising;

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

a power cable inserted through an inside of the pipe and which connects the power source and the electrical load;

wherein the power cable pulled out of an end part of the pipe inserted through the power-source-side through-hole, is restrained by a first cable guide provided inside the vehicle, and is wired to a connection part of the power source, and the end part of the pipe inserted through the power-source-side through-hole reaches as far as a position where the first cable guide is provided, and

wherein the pipe is supported by a through-hole seal member which has a pipe through-hole through which the pipe passes, and which closes 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 passed through pipe is supported via the seal resin.

3. The vehicle wiring structure according to claim 2, wherein the pipe through-hole is formed of the seal resin integrally with a grommet for protecting the power cable pulled out of the end part of the pipe from the edge of the end part.

4. The vehicle wiring structure according to claim 1, wherein a center of the pipe through-hole of the through-hole seal member is misaligned from a center of a closing part of the power-source-side through-hole of the through-hole seal member.

5. The vehicle wiring structure according to claim 1, wherein the pipe is made from metal and is grounded to a body earth 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 cable of the power source is disposed with a space therebetween in a vehicle right-to-left direction, and

wherein a second cable guide is provided which bends the power cable protruding in the vehicle front-to-back direction via the first cable guide, to a direction of the connection part of the power source and the power cable.
