ンスフア装置の潤滑構造。[Claims for Utility Model Registration] 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, comprising: A predetermined gap is provided between the pump pilot part and the bearing pilot part, and the bearing pilot part positions the oil pump in the axial direction to form an oil chamber between the oil pump and the bearing. A lubrication structure for a four-wheel drive transfer device, characterized in that a minute gap is formed between a housing and an inner gear, and oil leaked from an oil pump is supplied to a speedometer via a bearing.
