The purpose of the present invention is to eliminate the need to provide a backflow prevention mechanism, when installing two oil pumps as a hydraulic power source. The system is provided with a mechanical oil pump (17), an electric oil pump (18), a forward clutch (14), and a control valve unit (19). In this clutch hydraulic system for a vehicle, a main pump oil passage (26) leading from the mechanical oil pump (17) is connected to the control valve unit (19). A sub-pump oil passage (27) leading from the electric oil pump (18) is connected to a forward clutch oil passage (29) into which an oil passage outlet (29a) opens at an inside location closer to the clutch rotational axis CL than the clutch oil chamber (28) of the forward clutch (14). |
