PROBLEM TO BE SOLVED: To provide an automatic grease feeder for a hydraulic striking device to automatically feed grease which can be easily operated by anybody. SOLUTION: In the automatic grease feeder for the hydraulic striking device to feed grease to a breaker part of the hydraulic striking device by a grease cartridge 15 via an operation of a feed control unit 1, low-pressure oil discharged by the operation of the hydraulic striking device is fed to the feed control unit for a power source for pressurization. The pressure is applied inside the feed control unit, and grease from the grease cartridge is pumped to a breaker part of the hydraulic striking device. The negative pressure is applied in the feed control unit by stopping the hydraulic striking device, and the grease is sucked from the grease cartridge so as to be pumped to the breaker part of the hydraulic striking device.
