Claim:
1. A hydraulic-pressure control device comprising: a regulator comprising: a housing; a control piston fluid-tightly and slidably fitted in the housing; an input chamber provided at a rear of the control piston; and an output chamber provided in front of the control piston; and an input-hydraulic-pressure control device configured to control hydraulic pressure in the input chamber to move the control piston forward to raise hydraulic pressure in the output chamber and configured to control the hydraulic pressure in the input chamber to move the control piston backward to reduce the hydraulic pressure in the output chamber, wherein the input-hydraulic-pressure control device comprises a moving-direction control unit configured to: the input-hydraulic-pressure control device comprises a normal control unit configured to: wherein the pressurization-side set value is a value greater than the pressurization threshold value, and the reduction-side set value is a value less than the pressure-reduction threshold value.
