To make a device compact and facilitate the maintenance by vertically stacking a plurality of valves having an oil pressure takeout part and a switching spool on a valve case to constitute a valve unit, and mounting it on the vehicle body side between lateral lift arms.
An external oil pressure takeout valve 35 is provided with a switching spool 62 on a valve case 61 with its axial center being laterally set, and an oil pressure takeout part 35A is formed of a quick coupler capable of substantially attaching and detaching an oil pressure takeout hose. A plurality of the valves 35 are vertically stacked through an intermediate spacer 65 and a head spacer 66 and attachably and detachably mounted by a bolt 67. Since the valves 35 are provided between lateral lift arms 9, it never hinders the rising and falling motion of the lift arms 9. Further, the valve unit 35 is attachable and detachable in the state where a spacer 60 is mounted on an oil pressure housing 33, so that the maintenance can be further more facilitated.
