摘要： A grease fed into a metering pressure feeder (22) from a grease tank (10) is accurately weighed to be fed into an injection cylinder (30) and the entire grease in the injection cylinder (30) is injected from a nozzle (34). The nozzle (34) can advance toward an electric motor (60) so as to, bring a first packing (50) and a second packing (52) at a front (34a) of the nozzle (34) into close contact with an outer ring (66a) and an inner ring (66b) of a bearing (66), respectively. When in this state the grease is injected from an injection hole (34b), it is forced into the working space of rolling elements (66c) of the bearing (66) and filled into a grease pocket (68).
