器。[Claims for Utility Model Registration] A piston that is slidably provided with two chambers defined within the cylinder, and a damping device that generates damping force by restricting fluid flow between the two chambers. The force generating means is provided in a bypass path that receives and slides the hydraulic pressure of the pressure receiving chamber communicated with the defined chamber via a transmission path, and bypasses the damping force generating means by this sliding. a movable member that changes the opening degree of the variable throttle; a fixed throttle that is provided midway through the transmission path; and a fixed throttle that is movable as the piston slides and that adjusts the opening of the transmission path or bypass path according to the amount of movement. a retainer formed to be able to change a flow path area; a biasing device that biases the retainer in a direction to prevent movement of the retainer from a set position; and a biasing device that presses the retainer in a direction corresponding to the biasing device. A variable damping force shock absorber, comprising: a pressing means; and a damping force variable shock absorber.
