。 The interior of the cylinder is defined by the piston into an upper liquid chamber and a lower liquid chamber, while a reservoir chamber is provided in contact with a bottom valve disposed at the bottom of the cylinder, and the piston is provided with a reservoir chamber during its extension stroke. A damping force generation valve on the extension side is provided in the bottom valve, and the bottom valve is provided with a damping force generating valve on the extension side, which opens to displace liquid in the upper liquid chamber to the lower liquid chamber and generates a damping force. A variable damping force hydraulic shock absorber is provided with a compression side damping force generation valve that displaces and circulates liquid in the chamber into a reservoir chamber and generates damping force, in which a bypass passage is provided that connects the upper liquid chamber and the bottom valve. , to the bottom valve;
A first passage communicating between the lower liquid chamber and the reservoir chamber, and a second passage communicating between the bypass passage and the reservoir chamber are provided, and the first passage communicates with the lower liquid chamber and the reservoir chamber, and the first passage communicates with the lower liquid chamber and the reservoir chamber. A variable damping force type hydraulic shock absorber, characterized in that a damping force adjusting means is provided for adjusting the opening areas of the first passage and the second passage.
