ABSTRACT:
A hydraulic pressure control device of a load sensing type is provided. The hydraulic pressure control device includes a spring support disposed on a vehicle body side or wheel side for supporting a suspension spring, a support member tiltably disposed in the spring support for supporting a load of the suspension spring at three support portions, and a hydraulic pressure control valve mounted on the support member for controlling hydraulic pressure supplied to a braking unit mounted on a wheel from a source for generating hydraulic braking pressure. Thus, at least a portion of the force applied to one of the support portions can be applied to a control piston of the hydraulic pressure control valve.
