Abstract: <P>PROBLEM TO BE SOLVED: To shorten axial length in a shock absorber whose damping force can be regulated.  <P>SOLUTION: A piston 5 connected to a piston rod 6 is fitted slidably in a cylinder 2 having a hydraulic oil sealed therein. The damping force is generated to the sliding of the piston 5 by extension-side and compression-side damping force generating mechanisms 13, 14 in extension-side and compression-side passages 11, 12. A damping force generation mechanism 19 is provided in bypass passage 21, which bypasses the extension-side and compression-side damping force generating mechanisms 13, 14.
