摘要: The frame (3) of a vehicle body is constituted by left and right vertical plates (4), (5) and a bottom plate (6) coupling the vertical plates (4), (5) horizontally. In addition, a control valve device (33) and a control valve device (43) including a plural number of directional control valves are mounted in advance on a single mounting plate (32) together with a correction lever (49), a plural number of operation levers (62), (63) and link mechanisms (59) to (61) to obtain a lever/valve assembly (31). Then, the mounting plate (32) constituting of the lever/valve assembly (31) is attachable to or detachable from the left vertical plate (4) of the frame (3) by using bolts or the like. As a result, the efficiency of the assembly operation can be improved.
