Claims

[Scope of utility model registration request]

A cylinder defined by a piston into an upper liquid chamber and a lower liquid chamber, an outer cylinder disposed outside the cylinder and forming a reservoir chamber between the cylinder, and a cylinder disposed below the cylinder. During the compression stroke of the piston, the damping force generating means displaces and circulates the liquid in the lower liquid chamber to the reverser chamber to generate a damping force, and during the extension stroke of the piston, the valve opens to cause the liquid to flow from the reservoir chamber to the lower chamber. a base valve that allows liquid to flow to the liquid chamber; and a flow path disposed in the base valve that communicates the lower liquid chamber and the reservoir chamber in response to the liquid pressure in the cylinder during the compression stroke of the piston. A damping force variable hydraulic shock absorber is provided with a damping force adjusting means for adjusting the generated damping force by changing the cross-sectional area of the damping force adjusting means, in which a flow path passing through the damping force adjusting means is connected to the damping force generating means. A variable damping force type hydraulic shock absorber.
