係合弁を備えた油圧操作装置。A hydraulic power source capable of supplying a predetermined hydraulic pressure, a cylinder device having a differential piston that is supplied with the hydraulic pressure to both ends and is movable from one end to the other end due to a differential pressure, and provided between the cylinder device and the hydraulic power source. An oil supply valve that closes the flow path of the hydraulic pressure sent to one end of the cylinder device, and an oil drain valve that is driven by a command and has an operation part that opens the oil supply valve, the oil pressure of the oil pressure source is less than a predetermined value. The hydraulic operating device includes an engagement valve that engages with the oil supply valve when the oil supply valve is in an open position.
