PURPOSE: A hinged pin for a door of a vehicle is provided to prevent rust though water flows in the hinged pin portion by forming oil film to the hinged pin portion mounting bush. CONSTITUTION: A hinged pin(10) for a door of a vehicle has an incision part(20a), a flange(22), and an oil groove(11). The incision part is formed to a bush(20) to insert an installing part(10a) of the hinged pin. Therein, the incision part is inserted to the installing part by widening the incision part. Flanges are formed to both ends of a tubular body(21) to install the bush to the installing part. The oil groove is formed to an outer peripheral surface of the installing part. Thereby, one oil groove covers whole area by being formed spirally. Therefore, the hinged pin and the bush does not contact water directly though water flows in by forming oil film between the hinged pin and the bush.
