PROBLEM TO BE SOLVED: To simplify a connecting mechanism of wires between each door and a vehicle body by reducing the number of wires between each door and the vehicle body. SOLUTION: A main multiplex communication unit 12 in use for door electric equipment is arranged in the vehicle body 10 and a door side multiplex communication unit 13 is arranged in each door 11. The main multiplex communication unit 12 and each door side multiplex communication unit 13 are connected to each other via one wire w3 in use for a multiplex communication circuit. One common power circuit wire w1 for driving the electric equipment for each door 11 and one common earth circuit wire w2 are connected to a power circuit wire on the side of the vehicle body 10 and to an earth circuit wire, respectively. A connecting wire between the vehicle body 10 and each door 11 is constructed by three multiple communication circuit, power circuit and earth circuit wires w1, w2, w3. COPYRIGHT: (C)2004,JPO
