A power supply line is wired in a loop from a battery power supply, and a supply relay circuit is installed intermediatly of the power supply line such that power is supplied from the supply relay circuit to an electric load connected to a terminal unit of an intensive wiring line. By this arrangement, not only wires for control signals but also wires for power supply can be reduced. The terminal unit may serve also as the power supply relay circuit.

1. A power supplying apparatus in a vehicle, comprising:A. two transmission lines extending from one of poles of a power supply carried on said vehicle; B. a relay circuit having two input terminals individually connected to said transmission lines and having at least one output terminal, said relay circuit comprising on-off switches for making electric circuit on-off operation between one of said two transmission lines and said output terminal, and between another of said two transmission lines and said output terminal, respectively; and C. a connection circuit provided in said relay circuit for electrically connecting said two input terminals and said one output terminal to each other, said connection circuit disconnecting said output terminal by making either one of said on-off switches open when a failure is generated.
