A mechanical device main body in which a large number of liquid actuators for driving a movable mechanism part and a valve device for controlling the operation of the liquid actuators are fixed, and the mechanical device main body is arranged separately from the mechanical device main body and connected to the valve device via a pipe. And a hydraulic pressure source provided to store and discharge the working liquid, the valve device includes an electromagnetic switching valve that is switched by energization / de-excitation of a solenoid, and is pilot-operated by the electromagnetic switching valve. The liquid control valve is placed on the side surface separately from the electromagnetic switching valve, and a large number of manifolds that form a liquid circuit for controlling the operation of the liquid actuator are joined together with the flow path formed inside, and the mounting members are placed at both ends of the manifold. Provided integrally with each other by a tie rod, and at least one of the mounting members has a supply channel and a return channel for the working liquid that are connected to the hydraulic pressure source by piping, and each manifold has this channel. A through hole that penetrates through in the joining direction and is connected in series is provided.In this through hole, a conductor wire to be connected to the solenoid is accommodated, and this conductor wire is guided to the inside through one mounting member and from the power supply side with the built-in terminal block. A machine box provided with a terminal box to be connected to the power supply line of one of the machine members, and detachably fixed to the machine machine body by fastening members through plate-like mount legs provided on the outer surfaces of the two package members. .
