Claims

[Scope of utility model registration request]

a cylinder and a piston slidably disposed within the cylinder having a minimum cross-sectional area at its central location;
a piston having a space formed such that its cross-sectional area gradually increases upward and downward from the portion, and a port opened in the axial direction of the cylinder and communicating with the space;
a hollow piston rod connected to the piston at a lower end and having an upper end protruding outward from the cylinder;
A control rod that is inserted into the piston rod from above and rotatably supported in a liquid-tight manner, a portion of which is disposed within the space, and a guide portion is disposed between the portion above and below the guide portion. a control rod having a pair of threads cut in opposite directions, and a valve body disposed within the space so as to be movable in the axial direction guided by the guide portion of the control rod, the valve body a valve body having an orifice between the outer circumferential surface of the valve body and the inner circumferential surface of the piston when the valve body is located in the central portion of the space; and a spring seat screwed into each of the screws of the control rod. a spring seat that is held non-rotatably with respect to the piston and is movable in the axial direction of the control rod by rotation of the control rod; and a non-linear spring seat that is interposed between each spring seat and the valve body. Shock absorber including spring.
