The first pump in the lubricating device comprises:
It comprises a plurality of rotors arranged on the same axis and each having a dedicated suction port leading into the oil pan, and a spacer arranged between the rotors and provided with a discharge port shared by the adjacent rotors, By arranging multiple suction ports in the oil pan, it not only becomes possible to deal with uneven oil flow when the engine is tilted, but also prevents air from being sucked in if one suction port is exposed above the oil. However, as long as other suction ports exist in the oil, the rotor belonging to that suction port can function normally without being affected by air suction by other rotors, and this makes it possible for vehicles to run on steep slopes. It will not cause any hindrance.
