PURPOSE:To improve the durability of a pressure source in a cylinder control device that can drive both power steering control and cylinder control used for stabilizer control or the like by one pressure source. CONSTITUTION:A steering system actuated by a pressure fluid, and a travel control device also actuated by the pressure fluid are driven by a common pressure source and a flow dividing valve 9. An internal relief valve 2 for releasing the excess pressure fluid generated in a line where the pressure fluid passes is formed in the common pressure source. A relief valve with relief pressure set to the lower value than the relief pressure set to the internal relief valve 2 is disposed downstream of the flow dividing valve 9. |
