Zusammenfassung:	The utility model relates to an orbiting scroll plate and an oilless scroll vacuum pump, the rear end face of the orbiting scroll plate is provided with a bearing hole and a plurality of anti-rotation holes, the rear end face of the orbiting scroll plate is provided with at least one oil suction groove, the oil suction groove is positioned on the outer side of the anti-rotation holes, and the oil suction groove is used for installing an oil suction strip. And the oil absorption strip is used for absorbing grease or isolating grease from overflowing. The oil absorption grooves are formed in the rear end face of the movable scroll plate and located on the outer sides of the anti-rotation holes, and if grease overflows from the anti-rotation holes, the oil absorption strips installed in the oil absorption grooves can absorb the grease or isolate the grease, prevent the grease from continuously overflowing and prevent the grease from overflowing out of the movable scroll plate. Therefore, grease is prevented from
