緩衝器。An inner tube is slidably inserted into an outer tube, and an IJ-F valve is arranged in a passage through which hydraulic oil flows out as the inner tube contracts, and the initial opening of this IJ-F valve is controlled by a suspension spring. A spring bearing of the relief valve is held between the suspension spring and the detection spring facing the suspension spring so as to increase the amount of compression in accordance with the amount of compression of the spring. A hydraulic system characterized in that a spool is slidably inserted, a notched groove is formed halfway in the axial direction on the outer periphery of the spool, and a cylindrical seat formed in a valve holder is disposed on the outer periphery of the spool. buffer.
