Abstract

A shock absorber includes a hard-side damping element for applying resistance to a flow of liquid from a compression side chamber to an extension side chamber, a solenoid valve capable of changing an opening area of a compression side bypass passage for communicating the compression side chamber and the extension side chamber by bypassing the hard-side damping element, and a soft-side damping element provided in the compression side bypass passage in series with the solenoid valve. The hard-side damping element has an orifice and a leaf valve provided in parallel with the orifice. The soft-side damping element has an orifice having an opening area larger than that of the orifice.
