PURPOSE:To prevent lowering of lubricating oil pressure by supplying a fed-out fluid to a lubricating pressure oil path through a port disposed on a direct- coupled clutch control device at the time of feeding out a fluid to a working chamber. CONSTITUTION:When a solenoid valve A is excited, oil pressure is generated in an oil chamber 3, so that a direct-coupled clutch control valve 1 is pushed down against a spring 2 and oil pressure controlled by a primary regulator valve 9 is supplied to an oil chamber C through oil paths 13, 11 to connect a direct-coupled clutch B. On the other hand, oil pressure is supplied from the oil chamber 11 to an oil chamber 6, and the internal pressure of a torque converter D is lowered according to a direct-coupled clutch control pressure by oil pressure of a secondary regulator valve 7. At this time, however, as a discharge port 1b is opened to communicate with a port 1a, oil paths 17 and 18 communicate with each other. Accordingly, an oil paths 13 is communicated with an oil path 12 through the oil path 17, the ports 1a, 1b and the oil path 18 to prevent lowering of lubricating oil pressure applied to each portion. Thus, suitable lubrication can be conducted to each other.
