摘要： A hydraulic pressure control apparatus for a lockup clutch of a fluid transmission device. In a spool of the lockup relay valve, switching to a position on an engaging side (right half position) for engaging a lockup clutch is achieved by a signal pressure being input from a linear solenoid valve to a hydraulic oil chamber, and switching to a position on a releasing side (left half position) for releasing the lockup clutch is achieved by an urging member such as a spring force of a spring. Since the response is low with the switching by the spring force, the state of a vehicle is sensed by a sensor and, if quick release of the lockup clutch is necessary, a signal pressure from a solenoid valve is input to a hydraulic oil chamber to apply the spring force, and assists with a hydraulic pressure, thereby switching the spool to the releasing side. Accordingly, the response when the lockup relay valve is switched from the engaging side to the releasing side is enhanced.
