Abstract
A fluid pressure control device includes a first control valve that switches to supply a working fluid to the pressure chamber of a cylinder on which a load pressure by the load acts so as to control the extension operation of the cylinder, a second control valve that switches to discharge the working fluid in the pressure chamber so as to control the contraction operation of the cylinder, an operate check valve that is interposed between the pressure chamber and the second control valve and that interrupts the discharge of the working fluid from the pressure chamber when the operate check valve is switched to a closed state and a pilot valve that performs, with a pilot pressure, a pilot operation on the second control valve and that switches, with the pilot pressure, the operate check valve to an opened state.
