ショックアブソーバ。A shock absorber comprising a cylinder, a piston that is equipped with a damping force generator and a mechanism on an extension side and a contraction side, and that slides in the cylinder, and a piston rod that has the piston at its lower end, the shock absorber comprising: a hole extending in the piston rod and communicating with a chamber above the cylinder partitioned by the piston at a portion of the piston rod positioned within the cylinder when the piston rod is fully extended; a variable orifice provided at the lower end of the hole, the variable orifice communicating with the lower chamber of the cylinder defined by the piston and having a spherical surface at the upper portion; and a variable orifice that is retractably inserted into the hole. a control rod that can be operated from the outside, the lower end of which is provided with a spherical part that engages with the spherical surface of the variable orifice; and the control rod is sealed with respect to the hole above a portion where the hole communicates with the upper chamber of the cylinder. Shock absorber with variable damping force, including a control rod held in position.
