ことを特徴とする減衰力可変型液圧緩衝器。 A variable damping force mechanism adjusts a bypass amount of hydraulic fluid exchanged between an upper liquid chamber and a lower liquid chamber by vertical movement of a piston that defines an upper liquid chamber and a lower liquid chamber in the cylinder. A shaft hole is formed in the stud that integrally connects the piston to the piston rod and communicates with the lower liquid chamber, and a plurality of upper and lower holes with different diameters are bored in the circumferential direction of the stud to communicate with the shaft hole. Two rows of orifices, an annular path that communicates with the two rows of orifices and is formed in the fitting surface of the piston rod and stud, and a communication hole that is formed in the piston rod so as to connect this annular path to the upper liquid chamber. a shutter which is rotatably housed in the shaft hole of the stud and which selectively opens and closes the two rows of orifices above and below; In the variable damping force hydraulic shock absorber, which is configured with a check valve that blocks the flow of working fluid to one of the orifice rows, the annular passage and the communication hole are configured separately for each of the two upper and lower rows of orifices. A variable damping force hydraulic shock absorber featuring:
