Abstract
A damping unit of a shock absorber has: a damping valve provided in a second fluid passage, the damping valve being configured to impart variable resistance to a flow of working oil passing therethrough depending on positions; a bypass passage connected to the second fluid passage so as to bypass the damping valve; a solenoid valve configured to control the flow of the working oil in the bypass passage guided to the damping valve as a pilot pressure for switching the positions of the damping valve; a bottom-side restrictor portion configured to impart resistance to the flow of the working oil guided from the second fluid passage to the solenoid valve; and a rod-side relief valve configured to release the pressure in the bypass passage to a rod side chamber through the second fluid passage.
