There is provided a compact damping force variable shock absorber capable of implementing different adjustments for a compression-side stroke and an extension-side stroke as initial settings. A damping force variable device in one embodiment includes: a main valve that opens and closes to control flow of oil caused by sliding of a piston in a cylinder, thereby generating damping force; a pilot chamber into which a portion of the flow of the oil is introduced so that internal pressure is applied to the main valve in a valve-closing direction; a pilot valve that opens and closes to adjust the internal pressure of the pilot chamber; and a communication passage that communicates the pilot chamber with a rod-side oil chamber or a piston-side fluid chamber.
