。 In a transfer device that drives a wet multi-disc clutch mechanism by a first oil pump provided on the main shaft or a separate second oil pump driven by a DC motor, each discharge pressure of the first and second oil pumps is controlled. The hydraulic circuit is equipped with a regulator valve that regulates the pressure, a shift valve that switches the regulated line pressure, and a solenoid valve that controls the duty.In the emergency driving range, the regulator valve is forcibly deactivated and the high line pressure 1. A two-wheel drive/four-wheel drive switching device characterized by comprising a control means for controlling the pressure so as to obtain a relief valve pressure (relief valve pressure).
