る４輪駆動トランスフア装置。[Claims for Utility Model Registration] In a four-wheel drive transfer device that transmits the rotational force of a main shaft rotatably supported by a casing from a sprocket to a front drive shaft via a wet multi-disc clutch mechanism, when the vehicle is running, the The first oil pump installed on the main shaft supplies operating pressure to the piston fluid chamber, and when the pressure sensor detects that the operating pressure from the first oil pump has fallen below a specified value when the vehicle is stopped, the DC motor is driven. A four-wheel drive transfer device characterized in that working pressure is supplied from the second oil pump through an oil passage communicating with the piston liquid chamber.
