Zusammenfassung:	PURPOSE: Provided is an improved lubricating structure of a 2 inlet and 2 outlet type metering gear pump for supplying a lubricating polymer to the contact surface of a drive gear and a front plate using an inner pathway formed on a drive shaft. Therefore, the structure prevents burning and abnormal abrasion of the drive gear and the front plate. CONSTITUTION: A lubricating structure comprises: a drive shaft(7) formed by a lubricating polymer supply pathway(12) which is extended to a discharge hole(25) formed on the surface in which a drive gear comes into contact with a front plate(3); a supply groove formed at the cross-sectional part of a weir plate to supply the lubricating polymer to the supply pathway of the drive shaft; and a receiving slot formed on the surface in which the drive gear comes into contact with the front plate to receive the lubricating polymer discharged from the discharge hole.
