摘要： The frame of a vehicle body is constituted by left and right vertical plates and a bottom plate coupling the vertical plates horizontally. In addition, a control valve device and a control valve device including a plural number of directional control valves are mounted in advance on a single mounting plate together with a correction lever, a plural number of operation levers and link mechanisms to obtain a lever/valve assembly. Then, the mounting plate constituting of the lever/valve assembly is attachable to or detachable from the left vertical plate of the frame by using bolts or the like. As a result, the efficiency of the assembly operation can be improved.
