Zusammenfassung:The invention provides a fluid pressure control device. The device can reduce the fluctuation of MOD pressure output by a pressure adjusting valve due to the change of the discharge amount. The fluid pressure control device (100) comprises a fluid pressure pump (102), which absorbs lubricant from an oil tank (101) through an oil path (L01) and discharges the lubricant to an oil path (L02); a first pressure adjusting valve (103), which can adjust the pressure of the lubricant to the same level of the pipeline and discharges the lubricant to an oil path (L03) to supply the oil to pulleys (201 and 202); and a second pressure adjusting valve, which adjusts the pipeline pressure supplied to the second pressure adjusting valve to generate a MOD pressure, then outputs the MOD pressure to an oil path (L06), and discharges the residual lubricant, which is generated during the MOD pressure production process, to an oil path (L07). The oil path (L07) is connected to the oil path (L01).
