め弁とを含む、液圧緩衝器。 A hydraulic shock absorber in which two liquid chambers divided in a cylinder are communicated through a passage provided in a piston rod, and the flow rate of the liquid is adjusted by a valve mechanism disposed in the passage, the valve mechanism being , a sleeve having first and second passages of different diameters opened in the radial direction at portions spaced apart from each other in the axial direction; a first space communicating with the first passage outside the sleeve; A core arranged so as to form a second space with which the second passage communicates, the core having a passage portion having a diameter different from the diameter of the first passage, and a third passage communicating with the first space. The passage has a passage portion having a diameter different from the diameter of the second passage, and
a core provided with a fourth passage communicating with the space; and a plunger disposed within each of the spaces so as to be movable in the axial direction of the sleeve and capable of communicating with the third or fourth passage of the core. a plunger having a fifth passage and moved by an electromagnetic coil; and a check valve disposed in the third and fourth passages to prevent the flow of liquid when the piston rod is extended. and a check valve that allows liquid to flow during contraction.
