ルポンプ。[Claims for Utility Model Registration] An inner rotor supported by the drive shaft and an outer rotor meshing with the inner rotor are driven by the crankshaft via a rotation transmission mechanism, and rotate within a pump chamber whose one end is closed by a pump cover body. The lubricating oil pump is characterized in that the drive shaft is hollow so that oil pressure from the bearing hole side in which the base end portion of the drive shaft is supported is released to the distal end side through the inside of the drive shaft. Lubricating oil pump for internal combustion engines.
