Abstract
A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; and a valve that is configured to control a flow of the liquid in the flow passage. The flow passage formation part includes a first seat part that is provided radially outward of a flow passage port of the flow passage, protrudes from the flow passage port and contacts the valve, a second seat part that is provided radially outward of the first seat part, protrudes from the flow passage port and contacts the valve, and a circulation part having an orifice that allows the liquid to flow from the flow passage port toward the second seat part in a state in which the valve is in contact with the first seat part.
