1. A harness arrangement structure of a vehicle which is equipped with a motor to drive a driving wheel of the vehicle, a high-voltage battery to supply electricity to the motor for driving the driving wheel of the vehicle, a low-voltage battery, a main relay to be activated by the low-voltage battery for controlling ON or OFF of an electric supply from the high-voltage battery to the motor, wherein the motor is configured to drive the driving wheel of the vehicle when the electric supply from the high-voltage battery is ON, and a control unit to be activated by the low-voltage battery which includes a switch means to open or close of a feeder circuit for the main relay, the harness arrangement structure comprising:
a first harness connecting said small-voltage battery to said main relay; and a second harness connecting said main relay to said control unit, wherein said feeder circuit for the main relay is constituted at least by said first harness, said main relay, said second harness and said switch means which are connected in series from a plus-terminal side of the low-voltage battery to a vehicle-body ground side, and the first harness and the second harness are arranged to be adjacent to each other in a specified range having a specified length so that when the second harness in said specified range is damaged and electrically grounded to a vehicle body, the first harness in said specified range is damaged and electrically grounded to the vehicle body, whereby the electric supply from the high-voltage battery to the motor for driving the driving wheel of the vehicle becomes OFF whenever the second harness gets damaged. |
