Document Type and Number:
Japanese Patent JP2001159443
Kind Code:
A
Abstract:
To provide a hydraulic shock absorber, capable of effectively reducing wide vibrations including high-frequency vibration.
A cylinder 2 filled with operating liquid and a piston rod 4 to be retractably projected through a rod guide 3 provided on the end of the cylinder 2, are provided. A friction member 17 for providing the frictional resistance to the inserting/retracting operation of the piston rod 4 is provided between the rod guide 3 and the piston rod 4.
