Claims

[Claims for Utility Model Registration] (1) A piston is filled with fluid and is movable in the axial direction, and the inner diameter is gradually reduced in the direction of movement of the piston due to the action of a dynamic load. a tube configured such that a cross-sectional area of a first orifice formed between an inner circumferential portion and an outer circumferential portion of the piston gradually decreases as the piston moves due to the action of a dynamic body load; and one end of the tube. and a plug in which a second orifice is formed, the viscosity of the fluid being displaced by the piston being moved by the action of a dynamic load when passing through the first and second orifices. A shock absorber characterized by absorbing dynamic body load energy through resistance. (2) The inner diameter of the tube gradually decreases in the direction of movement of the piston due to the action of a dynamic load.
The shock absorber according to claim 1, wherein the shock absorber is constructed by forming a tapered portion that tapers in the direction of movement of the piston. (3) the tube is accommodated in the inner axial direction of a cylinder having an inner diameter larger than an outer diameter of the tube;
The fluid passing through the second orifice formed in the plug is returned to the back side of the piston through a fluid chamber configured between the inner periphery of the cylinder and the outer periphery of the tube. A shock absorber according to claim 1 of the utility model registration claim, characterized in that: (4) The buffer according to claim 1, wherein the cross-sectional area of the second orifice is externally variable.
