ことを特徴とするギヤポンプ。 In a gear pump, a lubrication groove is provided in a bearing part of a drive shaft that is integrally connected to a drive gear and rotationally drives the drive gear, and which guides fluid flowing inside the gear pump. The lubrication groove is provided from inside the gear pump to a position near the shaft end that does not substantially reach the end of the drive shaft, and the bearing portion between the position near the shaft end and the end of the drive shaft is A gear pump characterized in that the gear pump is formed in a shape that has a flow resistance greater than that of the bearing part, and is provided with a bleed passage that connects to the outside of the gear pump from a position near the shaft end and releases fluid after lubricating the bearing part to the outside of the gear pump. .
