A casing is provided in a power train of a four-wheel drive motor vehicle and supported on a body of the vehicle. A fluid-operated multiple-disk friction clutch is disposed in the casing. The clutch has a drive drum operatively connected to an input member of the power train and a driven drum operatively connected to an output member of the power train, and a piston slidably mounted in a piston chamber and operated by oil supplied to the piston chamber for engaging the drive drum with the driven drum. A hydraulic circuit having an oil pump is provided for exclusively supplying oil to the piston chamber.
