It includes: an inner cylinder which defines an inner chamber therein, where a piston is in slidable contact with the inner chamber; an outer cylinder which is arranged outside the inner cylinder and defines a reservoir chamber between the inner cylinder and the outer cylinder; and a damping-force control device (9) which controls a damping force by controlling a flow rate of an operating oil between the inner chamber and the reservoir chamber. The damping-force control device (9) includes a valve seat which is formed to externally project from the outer cylinder, and in which an opening (12a) for a first communicating channel (12) connected to the inner chamber and an opening (13a) for a second communicating channel (13) connected to the reservoir chamber are formed, a valve element (15) which opens and closes on the valve seat (11) by electromagnetic force, and controls a flow of the operating oil between the first communicating channel (12) and the second communicating channel (13), and a cap (17) which defines a variable pressure chamber (16) between the valve seat (11) and the valve element (15), and integrally holds the valve element (15) and the valve seat (11), where the variable pressure chamber (16) can be connected to the first communicating channel (12) and the second communicating channel (13). |
