PROBLEM TO BE SOLVED: To reduce the total weight of motor drive controller by decreasing the number of signal lines transmitting the drive control signal for motor, to reduce the labor of work for connecting a switch circuit through wires with a motor drive circuit by simplifying the connection work, and to suppress the product cost increase by reducing the labor of connection work and shortening the required length of wire. SOLUTION: The content of designated operation for controlling the driving of a motor are transmitted from a lock switch 9, a main ascend switch 11 and a main descend switch 13 through two wires 35, 39 connected with the switches 11, 13 to an ascend side relay 65 and a descend side relay 85 which switch the power supply for driving a motor on the side of assistant driver's seat depending on the content of designated operation. |
