器。[Claims for Utility Model Registration] A valve body in which the inside of a shock absorber is divided into two chambers, a damping force generating means that generates a damping force by restricting the flow of fluid between the two chambers, and said chamber. It slides by receiving the liquid pressure in the pressure receiving chamber, which is communicated with the created chamber via the throttle, and in response to this sliding, it is possible to change the cross-sectional area of the bypass passage that bypasses the damping force generating means. a movable member formed in the cylinder, a piston slidably provided in the cylinder, a member on the piston side and a member on the cylinder side so that an elastic force acts in a direction that suppresses the stroke of the piston from a neutral position. A variable damping force shock absorber, comprising: a spring interposed between;
