することを特徴とする油圧遠隔操作装置。 A piston connected to the main spool via a rod and housed in a cylinder so that an electromagnetic actuator that hydraulically operates the main spool of the directional control valve can freely move within a range substantially equivalent to the switching range of the main spool, and the piston. The control spool is separately provided between the pressure chamber and the pressure oil supply passage and the tank passage so as to supply and discharge pressure oil to each of the pressure chambers formed on both sides of the When the solenoid is energized, it moves to the switching position so that pressure oil with a pressure proportional to the excitation force is supplied to the corresponding pressure chamber, and when the solenoid is demagnetized, the pressure oil supply passage side is shut off and the tank passage is returned to the pressure chamber. In the hydraulic remote control device, the control spool of the solenoid valve comprises a solenoid valve configured to move to a position and a reaction spring provided in each of the pressure chambers so as to restrict the range of movement of the piston. It has an effective pressure receiving surface that receives an acting force in the direction of movement to the return position due to the hydraulic pressure of the pressure chamber, and a back pressure surface that receives the acting force in the direction of movement opposite to the effective pressure receiving surface and that receives the acting force of the hydraulic pressure of the tank passage. A hydraulic remote control device characterized by:
