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.

Abstract: A shock absorber is provided with a cylinder, a piston inserted into the cylinder and demarcating an interior of the cylinder into an extension side chamber and a compression side chamber, a piston rod joined to the piston, a damping passage, provided in the piston rod, that communicates with the extension side chamber and the compression side chamber, and a damping force adjustment valve provided in the damping passage. The damping force adjustment valve includes a damping force adjustment unit and a solenoid that drives the damping force adjustment unit to adjust a flow channel resistance. The piston rod includes a yoke into which the damping force adjustment valve is inserted, and a piston holding member mounted on the yoke. The yoke includes a through-hole opening from a side of the yoke and leading to the interior, and a groove provided on a perimeter of the yoke, extending from an anti-piston end, and leading to the through-hole.
