A cover structure of the oil pump is provided to reduce the frictional loss by forming the oil groove and the flow channel adjacent to the axis hole in which gear is axis-installed. An oil pump is equipped within the transmission. The supply of the oil is made with the circulation of gear. A cover structure of the oil pump includes the axis hole(110) formed on the cover unit(100) axis-supporting the gear; the oil groove(120) which is formed on the cover unit; the flow channel(130) which is connected to the oil groove and is formed on the outer circumference of the axis hole. The cover structure of the oil pump can reduce the frictional loss by taking advantage of the pressure generated in the suction/discharge of the oil pump. |
