おける油量調整装置。 A constant supply of pressure oil is ensured through the diversion oil path on the operation actuator side of the diversion mechanism, which separates and supplies the pressure oil from the hydraulic pump to the actuator for lifting the working part and the actuator for other operations. The remaining pressure oil supplied to the operating actuator side is supplied to the lifting actuator side oil path to raise and lower the working part. In the working vehicle, the detour oil path is provided with an oil amount adjustment valve mechanism that can open and close the oil amount adjustment valve mechanism to adjust the amount of pressure oil supplied to the lifting actuator side. A working vehicle characterized in that the valve mechanism is connected to a manual detection mechanism that detects that the lifting and lowering of the working part is caused by manual operation of an elevator operating tool and outputs a control command for closing the oil passage. Oil amount adjustment device.
