Abstract: A mono-tube shock absorber includes a cylinder, a piston slidably inserted into the cylinder, a piston rod coupled to the piston, an upper component group detachably attached to an end portion at a side of an extension-side chamber of the cylinder, a tube that is disposed inside a contraction-side chamber and has one end secured to an end portion at a side of the contraction-side chamber of the cylinder, a valve mechanism detachably attached to the other end side of the tube to partition a reservoir inside the tube, and a free piston that partitions the reservoir into a liquid chamber and a gas chamber.
