。 The piston area on the rod side of one hydraulic cylinder is formed to be the same area as the piston area on the head side of the other hydraulic cylinder, and the chamber on the rod side of the first hydraulic cylinder is made into the chamber on the head side of the other hydraulic cylinder. Both cylinders are connected via a tuned circuit, and each chamber on the head side of the first hydraulic cylinder and the rod side of the other hydraulic cylinder is connected to the pump and the tank via an electromagnetic directional control valve, respectively. In a spectacle designed to perform synchronized operation, the chamber on the rod side of the other hydraulic cylinder is connected to the synchronized circuit via a solenoid valve and a pressure reducing valve, and the synchronized circuit is connected to a relief valve and a pilot check. When one of the limit switches connected to the tank via a valve and installed on each hydraulic cylinder for confirming the backward stop position of the rod becomes inoperative, the electromagnetic directional control valve and solenoid valve connected to it are activated. A synchronization correction device for a plurality of hydraulic cylinders configured to supply fluid discharged from a pump to a synchronization circuit.
