PURPOSE: To obtain the subject device with simple structure without providing hydraulic pump by installing oiling circuit for oil to working device, etc., at the oil pressure-discharging side of gear device infinitely varying the speed of traveling device in going ahead and behind.
CONSTITUTION: Engine 1 is started, oiling circuit 5 is opened and pressurized oil from oil pressure-discharging side of infinitely variable gear device 3 is supplied to every revolving parts such as working device 4. Power is transmitted form the infinitely variable gear device 3 to traveling device 2 and car body is traveled with infinitely varying the speed in going ahead and astern, then a fixed work is performed. The oil pressure-discharging side of the infinitely variable gear device 3 is in a high-pressure state even in row revolution of the engine 1, thus the pressurized oil is able to be supplied.
