PURPOSE: A hydraulic pressure adjuster of a hydraulic pressure type wire compressor is provided to smoothly reciprocate a piston with a simple hydraulic pressure transmitter. CONSTITUTION: A hydraulic pressure adjuster of a hydraulic pressure type wire compressor is inserted into a hydraulic pressure inlet hole and an outlet hole(11,11'), and a hollow(12) in a piston rod(9). The inlet and outlet hole are punched to be opposite to both ends of the piston head of the piston rod. The adjuster forms a hydraulic in and out bar(14) having a hollow(13) in order to inject and discharge hydraulic pressure in the bar.
