Zusammenfassung:PROBLEM TO BE SOLVED: To operate a control means 7 without faults without affecting the voltage of a battery of the side connected with the means 7 for commanding a control of a working machine receiving power, even if the voltage of the battery of the side connected by operating a power generating means 9 for generating power for the machine receiving power. SOLUTION: A power supply device for the working machine comprises a commanding means 10 for commanding power supply to the power generating means 9, a rechargeable second battery 8 which is connected parallel with a rechargeable first battery 3 provided heretofore in a vehicle, and an opening/ closing means 11 provided in a circuit for connecting the batteries 3, 8 in parallel. In this case, the control means 7 is connected to the battery 3, and the means 9 is connected to the battery 8. When the means 10 is operated, the means 11 is opened.
