PURPOSE: A grease feeder is provided to easily supply grease having a high viscosity such that grease is not sticked to a peripheral wall of a grease feeding vessel by feeding grease using a grease feeding pump. CONSTITUTION: A grease feeder comprises a grease feeding vessel(10) and a grease feeding pump(12) inserted into the grease feeding vessel(10) so as to upwardly convey grease. The grease feeding vessel(10) is formed at an underside thereof with a slot(11). A piston ring(14) is movably installed in the grease feeding vessel(10). A lid(16), through which the grease pump(12) passes through, is provided at an upper end portion of the grease feeding vessel(10). A supporting plate(18) is attached to a lower end of the grease feeding vessel(10). A pressurized air injection hole(20) is formed in the lid(16) so as to inject pressurized air for lowering the piston ring(14) in the grease feeding vessel(10).
