Abstract
A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; a valve configured to control a flow of the liquid in the flow passage; a back pressure control valve configured to control a pressure in a back pressure chamber that provides a back pressure to the valve by inflow of the liquid; and an accommodation part that is in a tubular shape with one side opening end narrower than another side opening end, forms the back pressure chamber, and accommodates at least the valve and the back pressure control valve.
