特徴とする減衰力可変型液圧緩衝器。 A piston that divides the inside of the cylinder into an upper chamber and a lower chamber is fixed to the tip of the hollow piston rod that is removably inserted into the cylinder, and also communicates the upper chamber with the hollow hole of the piston rod. A communicating hole is formed, and a substantially cylindrical adjuster having an orifice whose rotation is restricted by a control rod and selectively communicates with the communicating hole is fitted into the hollow hole of the piston rod; A variable damping force type hydraulic shock absorber, characterized in that the rotation axis of the adjuster is supported by a lower thrust bush that is press-fitted into a hollow hole of a piston rod.
